I. B ACKGROUND
A. Factual History 1 In January 2021, Mr. Flechs , using the pseudonym “John Breezy,” began conversation s on the Kik online messaging platform with someone he believed to be a
14

- year - old boy. Suppl. ROA, Vol. II at 47, 114 . In fact, Mr. Flechs was messaging Sergeant John Haning, a member of the Rogers County, Oklahoma Internet Crimes Against Children Task Forc e. Id. at 41. 2 The minor told Mr. Flechs he was 14 years old and shared two photos of his face. Id. at 5 4; Suppl. ROA, Vol. III , Ex. 1 at 8 , 1 8

. Mr. Flechs responded that he was 35 and shared a photo of his face. Suppl. ROA, V ol

. II at 51; Suppl. ROA, Vol. III , Ex. 1 at 18

- 19

. 3 Over the next four days, Mr. Flechs and the minor discussed sexual topics in graphic detail, including oral sex, masturbation, the size of the minor ’ s penis, and their previous sexual experiences. See Suppl. ROA, Vol. III , Ex. 1 at 10

- 71

. Mr. Flechs asked

1 This factual summary derives from the evidence presented at trial.

2 We refer to Sergeant Haning as “the minor.”

3 We caution the reader that the communications between Mr. Flechs and the minor were sexually graphic . Because Mr. Flechs was convicted of a sexual crime and challenges the sufficiency of the evidence on appeal, we recount the communications to evaluate w hether the evidence was sufficient and to explain our decision. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 23 multiple times about the minor ’ s sexual desires, id. at 23 , 4 5 , and shared his own. At other points, the minor asked Mr. Flechs to “teach” him how to have sex. Id. at 29 , 42 , 56

. Mr. Flechs said , “ Lol That’s illegal, ” but continued the conversation. Id. at 56

. After they discussed meeting in person, including Mr. Flechs ’s telling the minor that he was driving near the minor ’ s home, id. at 60 , Mr. Flechs asked the minor if he would be going to the skatepark , i d. at 6 4

- 6 6

. The minor said yes, and when Mr. Flechs asked when the minor would be there, the minor asked Mr. Flechs to bring him a Dr. Pepper. Id. at 65

. Mr. Flechs agreed but noted that he “c[ould]n ’ t hang around” because he “[had] to take [his] daughter to gymnastics.” Id. He later remarked that he

was “ going [t]o be in a hurry to get to gymnastics so [he] c[ouldn] ’ t hang out but [he ’ d] get [the minor] a dr pepper.” Id. at 66 . He also said there would be “no teaching” during the encounter, a euphemism for sex. Id. When Mr. Flechs arrived at the skatepark, he handed two Dr. Pepper sodas to an officer posing as the minor. Officers then arrested him.
B. P rocedural History A grand jury indicted Mr. Flechs for attempted enticement of a minor in violation of 18 U.S.C. § 2422(b). Mr. Flechs testified at trial. A petit jury returned a guilty verdict. The district court sentenced Mr. Flechs to 120 months in p rison and five years of supervised release.
Mr. Flechs timely appealed. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 34 II. DISCUSSION On appeal, Mr. Flechs argues: (A) The trial evidence was insufficient to prove that he (1) intended to entice the minor or (2) took a substantial step toward enticement. (B) The jury instruction on the term “grooming” (1) violated Federal Rule of Evidence 605, (2) contained an unconstitutional presumption on the element of intent, and (3) misstated the law. We reject these arguments and affirm.
A. Sufficiency of the Evidence
Mr. Flechs argues the Government presented insufficient evidence to prove he (1) had the requisite specific intent to entice a minor or (2) took a substantial step toward enticement. H is appeal falters on a misunderstanding of the law of enticement and a misapplication of the standard of review for sufficiency of the evidence. We conclude the evidence was sufficient to convict him of attempt ed entice ment of a minor under
18 U.S.C. § 2422(b).
Standard of Review “We review de nov o whether the government presented sufficient evidence to support a conviction.” United States v. Sells , 477 F.3d 1226, 1235 (10th Cir. 2007) (quotations omitted)

. “In so doing, we view the facts in evidence in the light most favorable to the government. ” Id. (quotations omitted). “[W]e owe considerable deference to the jury’s verdict.” United States v. King , 632 F.3d 646, 650 (10th Cir. 2011) (quotations omitted). “ Our restrictive standard of review for a sufficiency of Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 45 the evidence question provides us with very little leeway.” Sells , 477 F.3d at 1235 (quotations omitted). 4 “While the evidence supporting the conviction must be substantial and do more than raise a mere suspicion of guilt, it need not conclusively exclude every other reasonable hypothesis and it need not negate all possibilities except guilt.” United States v. Erickson , 561 F.3d 1150, 1158

- 59 (10th Cir. 2009) (quotations omitted). “We will not weig h conflicting evidence or second

- guess the fact

- finding decisions of the jury , ” Sells , 477 F.3d at 1235 (quotations omitted) , and we defer to the jury’s assessment of a witness’s credibility, United States v. Rodriguez

- Flores , 907 F.3d 1309, 1312 (10th Cir

. 2018) . “[O] ur role is limited to determining whether a reasonable jury could find guilt beyond a reasonable doubt, based on the direct and circumstantial evidence, together with the reasonable inferences to be drawn therefrom.” Sells , 477 F.3d at 1235 (quotations omitted). Legal Background

a. Enticement The United States Code provides: Whoever .

. . knowingly persuades, induces, entices, or coerces any individual who has not attained the age of 18 years, to engage in prostitution or any sexual activit y for which any person can be charged with a criminal offense, or

4 Mr. Flechs moved for judgment of acquittal under Federal Rule of Criminal Procedure 29 after the Government ’ s case - in

- chief and renewed the motion after he testified and the defense rested

. He therefore preserved the issue for appeal. See United States v. Kelly , 535 F.3d 1229, 1234

- 35 (10th Cir. 2008). Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 56 attempts to do so, shall be fined under this title and imprisoned not less than 10 years or for life. 1 8 U.S.C. § 2422(b). “Congress’s repeated use of the word ‘any’ suggests that Congress intended [§ 2422(b)’s] reach to be broad.” United States v. Shill , 740 F.3d 1347, 1352 (9th Cir. 2014). We give the terms “persuade,” “induce,” and “entice” their ordinary meanings

. “To persuade is to induce by argument, entreaty, or expostulation into some mental position; to induce is to move and lead (as by persuasion or influence); and to entice is to draw on by arousing hope or desire.” United States v. Isabella , 918 F.3d 816, 831 (10th Cir. 2019) (quotations omitted). 5
b. Attempt To prove an attempt to commit a crime, the government must show (1) specific intent to commit the crime and (2) a substantial step toward completion of the crime. Id. i. Specific intent Specific intent is more than a general intent to commit the prohibited act. United States v. Blair , 54 F.3d 639, 642 (10th Cir. 1995). It requires the defendant to commit the act “voluntarily and purposely with the .

. . intent to do something the law forbids.” Id. (quotations omitted).

5 Although Mr. Flechs was actually communicating with Sergeant Haning , “i t is not a defense to

. . . enticement and exploitation of minors that the defendant falsely believed a minor to be involved

. ” United States v. Sims , 428 F.3d 945, 960 (10th Cir. 2005). Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 67 In United States v. Faust , 795 F.3d 1243 ( 10th Cir. 2015), we said § 2422(b) “criminalizes the sexual grooming of minors, regardless of any intent to consummate the illegal sexual activity.” Id

. at 1249 (quotations omitted). The statute thus “requires only that the defendant intend to entice a minor, not that the defendant intend to commit the underlying sexual act.” Id. (quotations omitted) ; s ee United States v. Dwinells , 508 F.3d 63, 65 (1st Cir. 2007) (rejecting “that section 2422(b) should be interpreted to include, as an additional element of the offense, an intent that the underlying sexual activity actually take place”). Stated differently, § 2422(b) “criminalizes an intentional attempt to achieve

a mental state

— a minor ’ s assent.” Faust , 795 F.3d at 1249 n.6 (quot ations omitted ). Other circuits have similarly found that the statute proscribes an attempt to achieve a minor’s assent. Thus , the statute “imposes no requirement that an individual endeavor to transform or overcome the will of his intended victim.” United States v. Waqar , 997 F.3d 481, 488 (2d Cir. 2021) (quotations omitted). And “a defendant can be found to

‘ persuade ’ or ‘ entice ’ even a seemingly ‘ willing ’ minor.” United States v. Zupnik , 989 F.3d 649, 654 (8th Cir. 2021). “The government must prove that the defendant intended to cause assent on the part of the minor, not that he acted with the specific intent to engage in sexual activity.” United States v. Lee , 603 F.3d 904, 914 (11th Cir. 2011) ( citations and quotations omitted). ii. Substantial s tep The government must also “ show that the defendant took a substantial step toward s the commission of the ultimate crime, and that such step was more than mere preparation

. ” Faust , 795 F.3d at 124 8 ( alterations and quotations omi tted). Whether the Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 78 defendant took a substantial step is a “highly fact

- specific inquiry.” Id. (quotations omitted). As we explained in United States v. Fleming , 66 7 F.3d 1098 (10th Cir. 2011): A substantial step must be something more than mere preparation, yet may be less than the last act necessary before the actual commission of the substantive crime. A step need not be the final step toward commission of a crime to constitute a substantial step. Thus, the fact that further, major steps remain before the crime can be completed does not preclude a finding that the steps already taken are substantial. Id. at 1107 (citations , alterations, and quotations omitted). For attempted enticement,

“ t h e government must prove that the defendant took a substantial step toward causing assent, not toward causing actual sexual contact.” Lee , 603 F.3d at 914. “In assessing substantial steps toward .

. . enticement to engage in sexual activity, we have drawn a rough line between ‘ harmless banter ’ and illegal inducement.” Isabella , 918 F.3d at 832 (quoting United States v. Thomas , 410 F.3d 1235, 1246 (10th Cir. 2005))

. We have recognized that a substantial step “can be accomplished by several means and is oft en carried out through a period of grooming.” Id

. at 833 ( citation and quotations omitted). 6 We have held , for example, that meeting or planning to meet with a purported minor following sexual conversations may be a substantial step. See Thomas , 410 F.3d

6 Though many enticement cases involve sexual grooming conversations, the Sixth Circuit in Unite d States v. Fox , 600 F. App’x 414 (6th Cir. 2015) (unpublished), said “[t]hat evidence of sexually explicit online or telephone conversations sufficed to convict other defendants under § 2422(b) does not mean that such evidence is necessary to prove attemp ted enticement or coercion.” Id. at 418. Fox is not precedential, but we find its reasoning instructive. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 89 at 1246; United States v. Munro , 394 F.3d 865, 870 (10th Cir. 2005). But “travel or a definite plan to travel is not necessary to constitute a ‘substantial step’ under § 2422(b).” United States v. Howard , 766 F.3d 414, 425

- 26 (5th Cir. 2014); see also United States v. Goetzke , 494 F.3d 1231, 1235

- 37 (9th Cir. 2007) (“[T]ravel by a defendant to meet a potential victim is probative, but not required .

. . .”). The dissent argues that a substantial step requires a prop osal for sexual activity as a matter of law

. Dissent at 2 0

- 21

. But t he statute and case law do not require a proposal , and such a categorical rule would run counter to our directive that “[t]he substantial step question is a ‘ highly fact

- specific inquiry

. ’ ” Isabella , 918 F.3d at 832 (quoting Faust , 795 F.3d at 1248)

. In § 2422(b) , “Congress has made a clear choice to criminalize persuasion and t he attempt to persuade.” Faust , 795 F.3d at 1249. A ttempted enticement under § 2422(b) requires proof of a substantial step toward “ persuad [ing] , induc [ing] , entic [ing] , or

coerc [ing]” a minor “ to engage in prostitution or any sexual activity .” 18 U.S.C. § 2422(b). A crime this broadly defined “can be committed in many different ways. ” Stokeling v. United States , 139 S. Ct. 544, 554 (2019); see United States v. Booker , 543 U.S. 220, 251 (2005) (“ [A] n act that meets the statutory definition [of a crime] can be committed in a host of different ways

. ”). Although evidence of attempted enticement may often include a sexual proposal, we have not held a proposal is necessary
. 7 And other circuits have found a substantial

7 The dissent mistakenly relies on United States v. Lopez , 4 F.4th 706 (9th Cir. 2021), and United States v. Hart , 635 F.3d 850 (6th Cir. 2011), to i nsist that other circuits Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 910 step based on evidence other than a proposal or acceptance of a proposal for sexual acti vity. See, e.g. , United States v. Clarke , 842 F.3d 288, 298 (4th Cir. 2016) (finding the defendant took a substantial step when he “brought candy to what he believed was a weekend visit” with two minors because “[a] reasonable jury could have concluded th at [the] [d]efendant intended to use the candy to entice [the minors] to engage in sex acts”); United States v. Hensley , 574 F.3d 384, 391 (7th Cir. 2009) (finding “more than enough for a jury to find a substantial step” where the defendant “groom[ed] [the victim] for sex by conversing with her using multiple online personas,” “arrange[d] a meeting place and

have “appeared to assume ” a sexual proposal is always necessary for a § 2422(b) attempt conviction. Dissent at 5

- 6

. In both cases, the defendant had proposed sexual activity. T he issue presented on appeal was not whether a proposal was required but whether the defendant’s proposal was for a “ sexual activity for which any person can be charged with a criminal offens e”

— a different element of the offense. 18 U.S.C. § 2422(b). In other words, both cases concerned an element of the attempted enticement offense that is not at issue here. In Lopez , t he defendant argued he could not be prosecuted in Guam, where the § 2422(b ) offense occurred, for the sexual acts he proposed. 4 F.4th at 718

- 19; see id. at 719 (“[The defendant] asks us to interpret Section 2422(b) as requiring the Government to charge a predicate offense and to prove Guam would have had jurisdiction to prosec ute him for said predicate offense.”). Lopez held that a defendant who has proposed sexual conduct may be convicted under § 2422(b) if the “proposed sexual conduct .

. . would be criminal in a relevant territorial jurisdiction.” Id. at 726. It did not a ssume that a proposal is always required. In Hart , the Sixth Circuit held that “[t]o convict [the defendant] under 18 U.S.C. § 2422(b), the jury had to unanimously agree .

. . that the sexual activity that [the defendant] attempted to persuade [the minor] to engage in would have been chargeable as a crime under Kentucky law.” 635 F.3d at 855. The court rejected the defendant’s argument that “the jury should have been required to identify in its verdict form which of the Kentucky statutes it unanimously co ncluded [he] violated.” Id. Like Lopez , Hart did not assume that a sexual proposal was always required for a § 2422(b) conviction. It instead held that the jury need not unanimously agree on which law the proposed act would violate. Id. at 856. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1011 time,” and “ actually traveled to the meeting place” (quotations omitted)) ; United States v.
Fox , 600 F. App’x 414, 418 (6th Cir. 2015) (unpublished) ( f inding sufficient evidence for a § 2422(b) attempt where the defendant “flatter[ed]” the minor and “purchased expensive gifts for her”). 8
The dissent’s strict proposal requirement would enable child predators like
Mr. Flechs to avoid § 2422(b) liability through subtle manipulation by carefully avoiding requests for sex . Courts have emphasized how § 2422(b) enticement defendants manipulate children. See , e.g. , United States v. Zobel , 696 F.3d 55 8 , 565 (6th Cir. 2012) (stating the district court “ noted [ the defendant ] , while not forcing himself upon the minors, had carefully cultivated and manipulated them ” (alterations and quotations omitted) ) ; United States v. Kempter , 29 F.4th 960, 966 (8th Cir. 2022) ( holding “ [t] he district court did not clearly err in concluding this was a case of grooming” in which the defendant “manipulated [the victim’s] weakness ” ). “Congress intended [§ 2422(b)’s] reach to be broad

. ” S hill , 740 F.3d at 1352 . We

see no reason to limit attempted enticement to cases with proposals. 9

8 Alt ho ugh each of these cases included a proposal, we do not read them to say that the courts necessarily “upheld the finding of a substantial step based on the defendant’s sexual proposals.” Dissent at 1 8

. 9 “[O]ur aim is not to decide whether [a defendant’s] conduct is at least as ‘criminal’ as the conduct of others convicted under section 2422(b). Each of our precedents holds no more than that a reasonable jury could have found that the defendant at issue violated section 2422(b). Not surprisingly, none [of our precedents] guesses at or purports to have identified the minimum conduct that section 2422(b) proscribes.” Lee , 603 F.3d at 916. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1112 Analysis

a. Specific i ntent Mr. Flechs argues the Government adduced insufficient evidence to prove he specifically intended to entice the minor because “[e]ach time [the minor] propositioned
Mr. Flechs for sex, Mr. Flechs declined.” Aplt. Br. at 13. We are not persuaded. First, Mr. Flechs m isunderstands the law. A defendant need not desire to have sex with a minor to satisfy the intent element of § 2422(b). 10 The statute “requires only that the defendant intend to entice a minor, not that the defendant intend to commit the underlying sexua l act.” Faust , 795 F.3d at 1249 (quotations omitted). A defendant may be liable for enticement even if the minor propositioned the defendant or the minor was otherwise eager, predisposed, or willing to engage in proscribed sexual acts. See Zupnik , 989 F.3d at 654. The appropriate inquiry, therefore, is whether the Government presented sufficient evidence to prove Mr. Flechs intended “ to draw [ the minor ] on ” to commit a proscribed sexual act “ by arous [ing] [the minor ’ s] hope or desire. ” Isabella , 918 F.3d at 831 (quotations omitted). Second, th e Government introduced sufficient evidence to prove Mr. Flechs had specific intent to entice the minor. At trial, Mr. Flechs admitted that he “introduced sexual topics” in the Kik conversation. Suppl. ROA, Vol. II at 113. The minor made multiple efforts to convince Mr. Flechs to meet to have sex. Early in their conversation s ,

10 Though “a jury could reasonably infer that Mr. Flechs had wanted to engage in sex with [the minor].” Dissent at 3. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1213 the minor stated that he “would like to meet [ Mr. Flechs] .

. . [and] see what [he and
Mr. Flechs] do

. ” Suppl. ROA, Vol. III , Ex. 1 at 7

. The minor reiterated the overture, asking Mr. Flechs, “What would u like to do if we meet?” Id. at 16 . When Mr. Flechs responded that they could meet at a skatepark, the minor responded , “ F un and then � � � � � � . ”
Id. The minor also repeatedly asked Mr

. Flechs to “teach” him how to have sex. Id. at 29, 42, 56

. Amidst the minor ’ s statements , Mr. Flechs engaged in a highly graphic sexual discussion with the minor from which a rational jury could infer Mr. Flechs ’ s intention to “arous [e] [the minor ’ s stated] hope or desire” for sex. Isabella , 918 F.3d at 831 (quotations omitted)

. For example, Mr. Flechs told the minor in detail about his sexual experiences with a “cousin [who] was 12 or 13” (when Mr. Flechs “ [ w ] as 16”) . Suppl. ROA, Vol . III, Ex. 1 at 33

- 34

. They also discussed Mr. Flechs ’ s desire to “[c]aress whoever all over then please them with [his] mouth

. ” I d. at 53

. During the conversation s , Mr. Flechs also asked about the size of the minor ’ s penis, id. at 26 , 40

- 41 , and asked him, “ W hat do you want done to you [ ? ] , ” i d. at 23

. Mr. Flechs also asked if the minor had “been [masturbating] while [ Mr. Flechs had ] been talking to [him],” id. at 51 , and asked multiple times whether the minor had “finish[ed],”
i d. at 51 , 55

. He also messaged the minor several times when he knew the minor ’ s purported guardian was away

— including once at 4:25 a.m. to tell the minor he was “driving by [his] area again.” Id. at 60

- 61

. Even though Mr. Flechs stated he wanted to meet in a “[v]ery public place, ” a reasonable jury could understand t hese messages as Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1314 indicat ing Mr. Flech s ’ s wish to meet the minor in person without adult supervision. Id. at 59

. A reasonable jury thus could have found that Mr. Flec hs intended to entice the minor because the conversation s “dr[e]w [the minor] on by arousing hope or desire” for

sex. Isabella , 918 F.3d at 831 (quotations omitted). A jury therefore “could find [the intent element satisfied] beyond a reasonable doubt, b ased on the direct and circumstantial evidence, together with the reasonable inferences to be drawn therefrom.” Sells , 477 F.3d at 1235 (quotation s omitted).
Mr. Flechs argu es his statements to the minor that he did not desire to have sex with him prove d he lacked the requisite specific intent

. 11 This argument reflects a cramped view of his statements to the minor, which were replete with graphic sexual descriptions and innuendo. See Suppl. ROA, Vol. III, Ex. 1. “[R]ather than examining the evidence in bits and pieces, we evaluate the sufficiency of the evidence by considering the collective inferences to be drawn from the evidence as a whole.” United States v. Brooks , 438 F.3d 1231, 1236 (10th Cir. 2006) ( alterations and quotations omitted). Mr. Flechs’s argument fails to overcome our standard of review.

11 Mr. Flechs did not unambiguously say no to sex ual activity with the minor

. See Suppl. ROA, Vol. III , Ex. 1 at 15 (responding “Yeah” to the minor asking if Mr. Flechs “want[ed] to [have sex with a man] a gain”); id. at 16 (responding to the minor’s proposition by saying “Lmao We can be friends”); id. at 39 (responding to the minor’s request that Mr. Flechs “be a teacher” with “Lmao I’ve forgotten the male experience”); id. at 56 (responding to the minor’s request “[t]o be taught” with “Lol Thats illegal”); id. at 59

- 60 (responding to the minor asking “ [ w ] ho’s [sic] hot dog” they would be eating with “Perv Hit me up tomorrow”). Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1415 “Even when a defendant, as here, denies having the requisite intent, a jury may disbelieve the defendant if his words and acts in the light of all the circumstances make his explanation seem improbable.” United States v. Porter , 928 F.3d 947, 957 (10th Cir. 2019) ( alterations and quotations omitted). The jury “was entitled to consider ”
Mr. Flechs’s “demeanor on the witness stand as evidence of the truthfulness of his tale.” United States v. Richard , 969 F.2d 849, 857 (10th Cir. 1992). A reasonable jury could have found Mr. Flechs ’ s statements suggesting he did not intend to have sex with the minor were not credible when considered alongside his graphic, sexual conversations with the minor. Our “restrictive standard of review for a sufficiency of the evidence question provides us with little leeway” to upset that finding. Sells , 477 F.3d at 1235 (quotations omitted). W e cannot “ second

- guess th [ at] fact

- finding decision [] of the jury ,” id. ( quotations omitted), because “[i]t is the province of the jury, rather than of the appellate court, to weigh the credibility of witnesses and to judge conflicting testimony , ” United States v. Moya , 5 F.4th 1168, 1187 (10th Cir. 2021) (quotations omitted). We must

“ resolve credibility issues in favor of the verdict. ” United States v. Meacham , 115 F.3d 1488, 1495 (10th Cir. 1997)

. b. Substantial step
Mr. Flechs argues the trial evidence was insufficient to prove he took a substantial step toward enticement. We disagree. First , he contends the “pre

- meeting messages must make it clear that the purpose of the meeting is to engage in sexual activity with the minor.” Aplt. Br. at 19. And he Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1516 asserts t he evidence did not prove that “had the police not intervened, [he] would have persuaded and encouraged [the minor]

— while dropping off the soda

— to agree to someday have sex with him.” Aplt. Reply Br. at 11. But this argument is again premised on a misunderstanding of the law. As discussed above, the inquiry is not whether Mr. Flechs took a substantial step toward having sex with the minor but whether Mr. Flechs took a substantial step toward enticing the minor. A defe ndant may entice a minor even without an “inten[tion] to commit the underlying sexual act.” Faust , 795 F.3d at 1249 (quotations omitted). Second, Mr. Flechs maintains that his sexual conversations and meeting with the minor were merely preparatory. See Aplt. Br. at 16

- 20. Even if that were a plausible reading of the evidence, under the applicable standard of review, we cannot say the evidence was insufficient to support conviction

. Mr. Flechs’s sexually graphic and suggestive messages and his actions to meet with the minor were sufficient.
Mr. Flechs’s grooming messages to the minor were relevant not only to his intent but also to whether he took a substantial step toward enticement. See Howard , 766 F.3d at 425 (“ [G] rooming behavior plus other acts strongly corroborative of intent to entice illegal sex

— such as detailed discussions to arrange a meeting with the minor victim

— can suffice to establish a substantial step under § 2422(b)

. ”); Goetzke , 494 F.3d at 1235

- 37 ( holding grooming plus a proposal to meet was a substantial step) ; Lee , 603 F.3d at 904 ( holding grooming conversations alone m a y be a substantial step). And here, the jury was instructed that “‘grooming’ can constitute a ‘substantial step.’” ROA, Vol. I at 43

. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1617 “In assessing substantial steps toward [enticement], we have drawn a rough line between ‘harmless banter’ and illegal inducement.” Isabella , 918 F.3d at 832 (quoting Thomas , 410 F.3d at 1246). A reasonable jury could have found :

• Mr. Flechs’s graphic descriptions of his own sexual experiences as a minor, as well as his current sexual desires, and his invasive questions about the minor’s penis and masturbation

— continuing over four days

— wer e hardly “harmless banter , ” i d

. , and instead were “enticing communications , ” United States v. Davis , 985 F.3d 298, 305 (3d Cir. 2021)

.

• Beyond Mr. Flechs’s highly sexualized conversations with the minor, his agreeing
to meet escalated matters and “ dr [e]w [the minor] on by arousing hope or desire”

— the definition of enticement. Isabella , 918 F.3d at 831 (quotations omitted) ; Davis , 985 F.3d at 305

.

• Mr. Flechs crossed the substantial

- step line when he went to an in

- person meeting at the skatepark , perha ps even sooner when he was driving in the minor’s neighborhood “again” and knew the minor’s guardian was away. Suppl. ROA, Vol. III , Ex. 1 at 60

- 61

. 12

12 Although Mr. Flechs ’s driving through the minor’s neighbor hood is not essential to affirm, it is not, as the dissent contends, a different “ theory” untethered from the jury instructions

. Dissent at 9 n.2. At trial, t he prosecution presented this evidence, which wa s consistent with the jury instructions. The dissen t cites McCormick v. United States , 500 U.S. 257 (1991), which reversed a circuit court for “announc ing a [new] rule of law” and then applying “legal and factual grounds that were never submitted to the jury” to determine that the evidence was sufficient. Id. at 269

- 70. But t hat did not happen here. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1718 The foregoing is consistent with our cases in which we have held that arranging or travelling to meet a minor after exchanging enticing messages may be a substantial step toward enticement. In Thomas , we held the defendant took a substantial step toward enticement “the moment he began making arrangements to meet [the purported minor], notwithstand ing the lack of evidence that he traveled to the supposed meeting place.” 410 F.3d at 1246. And in Munro , we found the defendant “took a substantial step towards completion of the crime by actually going to [a] prearranged meeting place

. ” 394 F.3d at 86 9- 70 ; s ee also United States v. Berg , 640 F.3d 239, 246 (7th Cir. 2011) (noting the defendant “d[id] not dispute that a face

- to

- face meeting in the course of a grooming process can be sufficient proof of a ‘substantial step’ toward the completion of

a § 2422(b) attempt”). Under the requisite “‘ highly fact

. Isabella , 918 F.3d at 832 (quoting Faust , 795 F.3d at 1248)

. A rational jury could find Mr. Flechs took a substantial step toward enticement b y exchang ing sexual messages with the minor, arrang ing to meet him, and travelling to the meeting place. Third , Mr. Flech s argues he had reasons unrelated to sex or enticement to go to the skatepark, including “an innocent desire to meet [the minor] in person and satisfy a curiosity about whether [the minor] was a real teenager or even a real person.” Aplt. Br.
at 22

- 23. He again skirts the standard of review. “ [T] he evidence supporting the conviction

. . . need not conclusively exclude every other reasonable hypothesis and it need not negate all possibilities except guilt.” Erickson , 561 F.3d at 1158

- 59 (quotations Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1819 omitt ed). “It is for the jury, as the fact finder, to resolve conflicting testimony, weigh the evidence, and draw inferences from the facts presented.” United States v. Keck , 643 F.3d 789, 793 (10th Cir. 2011). In sum, the jury ’ s determination that Mr. Flechs took a substantial step toward enticement was both reasonable and supported by sufficient evidence. We cannot “second

- guess th [at] fact

- finding decision[] of the jury.” Sells , 477 F.3d a t 1235 (quotation s omitted). 13

* * * * Viewing the evidence in the light most favorable to the Government, we determine that “a reasonable jury could find guilt beyond a reasonable doubt, based on the direct and circumstantial evidence, together with the reasonable inferences to be drawn therefrom.” Id. (quotations omitted). We affirm.

13 Even if we accept the dissent’s proposal requirement, a reasonable jury could infer that Mr. Flechs’s graphic messages to the minor proposed sexual acts. See, e.g. , Suppl. ROA, Vol. III, Ex. 1 at 10 (“Caugh t my friend’s boys sucking each other off and it reminded me of all the fun I had growing up.”); id. at 23 (asking the minor, “What do you want done to you[?]”); id. at 48

- 49 (telling the minor he was going to masturbate and asking if the minor was “[t]rying to give [him] a target” by sending a winking face emoticon)

. In closing argument, the Government pointed out that Mr. Flechs ask ed the minor, “What do you want done to you[?],” Suppl. ROA, Vol. II at 124, and argued, “There is no doubt in this ca se that .

. . [Mr. Flechs] was intimating to the child the things that he would like to do,” id. at 132; see Black’s Law Dictionary (11th ed. 2019) (defining “proposal” as including “a suggestion”). Evidence of an implicit proposal wa s consistent with the jury instructions and the Government’s grooming argument

. And u nder our standard of review, we determine whether a reasonable jury could have convicted based on the evidence, see United States v. Thomas , 749 F.3d 1302, 1314 (10th Cir. 2014), including an y evidence of a substantial step. The dissent’s cases to suggest otherwise, United States v. Woodard , 5 F.4th 1148 (10th Cir. 2021), and United States v. Chavez , 976 F.3d 1178 (10th Cir. 2020), did not involve sufficiency

. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 1920 B. Jury Instruction The Government proposed and the district court adopted the following jury instruction without objection: Definition of “Grooming” “Grooming” refers to deliberate actions taken by a defendant to expose a child to sexual material; the ultimate goal of grooming is the formation of an emotional connection with the child and a reduction of the child ’ s inhibitions in order to prepare the c hild for sexual activity. “Grooming” can constitute a “substantial step.” ROA, Vol. I at 43 (capitalization altered without notation).
Mr. Flechs argues the district court erred in instructing the jury on the meaning of “grooming,” asserting the instruction constituted (1) error because it was impermissible judicial testimony in violation of Federal Rule of Evidence 605, (2) plain error because it established a mandatory presumption on the element of intent, and (3) plain error because it misstated the law regarding substantial step. Each of these arguments fails. As a general matter, “[ w] e review [a] district court ’ s decision to give a particular jury instruction for abuse of discretion. ” United States v. Toledo , 739 F.3d 562, 567 (10th Cir. 2014). We review jury instructions as a whole “de novo in the context of the entire trial to determine if they accurately state the governing law and provide the jury with an accurate understanding of the relevant legal standards and factual issues in the
case.” United States v. Jean

- Pierre , 1 F.4th 836, 846 (10th Cir. 2021) (alterations and quotations omitted). Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 2021 Rule 605 Rule 605 provides, “The presiding judge may not testify as a witness at the trial.” It also states, “A p arty need not object to preserve the issue.” We therefore review de novo whether a district court violated Rule 605. See United States v. Andasola , 13 F.4th 1011, 1014 (10th Cir. 2021)

.

a. Legal background
“T he district court violates Rule 605 when it adds to the record evidence.” Id.
at 1016 (quotations omitted). “The purpose of jury instructions is to give jurors the correct principles of law applicable to the facts so that they can reach a correct conclusion as to each element of an offense according to the law and the evidence.” United States v. Kahn , 58 F.4th 1308, 1317 (10th Cir. 2023). An instruction on the applicable law falls outside Rule 605 because the court is not “testify[ing] as a witness.” Fed. R. Evid. 605. As one leading treatise states , “ [t] he most important factor” in d etermining whether a court ’ s statement triggers Rule 605 “ should be whether the judge ’ s statement is essential to the exercise of some judicial function or is the functional equivalent of witness testimony

. ” 27 Charles Al an Wright & Arthur R. Miller, Federal Practice and Procedure § 6063 (2d ed. rev. 2023). “ C riminal

- statute elements often contain terms needing defining.” Moya , 5 F.4th at 1180 . And “courts commonly provide jury instructions that define an element ’ s terms separate from the element itself.” Id. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 2122 b. Analysis
In Faust , we said that § 2422(b) “criminalizes the sexual grooming of minors, regardless of any intent to consummate the illegal sexual activity.” 795 F.3d at 1249 (quotations omitted). The term “g rooming” thus carries legal significance because we have interpreted the statute to proscribe such behavior. The district court ’ s instruction relied in substantial part on Isabella , see 918 F.3d at 833, and accurate ly restate d our caselaw . It did not imp roperly “add[] to the record evidence

. ” Andasola , 13 F.4th
at 1016 (quotations omitted). Rather, it was comparable to “provid[ ing ] [a] jury instruction[] that define[d] an element’s terms separate from the element itself.” Moya , 5 F.4th at 1180. We fin d Fox , 600 F. App ’ x 414 , persuasive. There, the Sixth Circuit rejected a challenge to a substantially similar grooming instruction because the instruction “adequately informed the jury of the relevant considerations and provided a basis in law for aiding the jury in reaching its decision.” Id. at 420 (quotations omitted)

. 14 The instruction thus did not violate Rule 605.
Mr. Flechs argues that our opinion in Andasola demonstrates the instruction here

was err oneous . But his reliance on Anda sol a is misplaced. There, the judge instructed the jury: “ [T]here is only one video that exists in this case.

. . . To the extent there was

14 Consistent with the district court here , courts have instructed on the meaning of “pyramid scheme,” see , e.g. , United States v. Gold , 177 F.3d 472, 478 (6th Cir. 1999), “check kiting,” see , e.g. , United States v. M ontgomery , 980 F.2d 388, 392

- 93 (6th Cir. 1992); United States v. Bonnette , 781 F.2d 357, 360 n.6 (4th Cir. 1986), and “churning,” see , e.g. , Davis v. Merrill Lynch, Pierce, Fenner & Smith, Inc. , 906 F.2d 1206, 1212

- 13 (8th Cir. 1990), even though none of these terms appeared in the underlying statute of conviction

. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 2223 any implication that another video exists, that is not an accurate statement. There is only one video. ” 13 F.4th at 1014 (quotations omitted) . We held the instruction was

err oneous because it “int roduced new evidence to the jury by deciding a disputed factual issue for the jury,” namely whether there was only one video. Id. at 1016. The grooming instruction here added no such factual finding to the trial record and instead provided the jury a def inition to aid its application of the law to the evidence. Presumption
Mr. Flechs next argues the grooming instruction established a mandatory presumption on the intent element . H e claims it instructed that if the jury found
Mr. Flechs had “expose[d] a child to sexual material,” the jury must also find that he intended to “prepare the child for sexual activity.” ROA, Vol. I at 43 (capitalization altered without notation); see Aplt. Br. at 41

- 4 3

. Mr. Flechs (1) misreads the instruction

a nd (2) has failed to show plain error
.

a. Standard of review
Because Mr. Flechs did not object to the instruction at trial, we review for plain

error. 15 Plain error review requires Mr. Flechs “to establish that (1) the district court

15 The Government argues Mr. Flechs invited the alleged error because he consented to the instruction. Aplee. Br. at 33. “Under the invited error doctrine, this [c] ourt will not engage in appellate review when a defendant has waived his right to challenge a jury instruction by affirmatively approving it at trial.” United States v. Cornelius , 696 F.3d 1307, 1319 (10th Cir. 2 012). I nvited error must be clear from the record. See United States v. Zubia

- Torres , 550 F.3d 1202, 1207 (10th Cir. 2008). Here, it is unclear whether Mr. Flechs’s attorney consented to the instruction itself or to the district court’s statement about when it planned to give the instruction. See Suppl. ROA, Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 2324 committed error; (2) the er ror was plain

— that is, it was obvious under current well

settled law; (3) the error affected the defendant ’ s substantial rights; and (4) the error seriously affected the fairness, integrity, or public reputation of judicial proceedings.” United States v. Booker , 63 F.4th 1254, 1258 (10th Cir. 2023) (alterations and quotations omitted). Mr. Flechs must show plain error “even when the underlying error is constitutional.” United States v. Gonzalez

- Huerta , 403 F.3d 727, 733 (10th Cir. 2005) (en banc) ; see Un ited States v. Chavez , 229 F.3d 946, 951 (10th Cir. 2000). b. Legal background A jury instruction may not establish an evidentiary presumption that requires the jury to find that the prosecution satisfied an element of the charged offense. See Francis
v. Fra nklin , 471 U.S. 307, 312

- 13 (1985). We distinguish between a mandatory presumption and a “ permissive inference. ” Patton v. Mullin , 425 F.3d 788, 804 (10th Cir. 2005). A mandatory presumption “ instructs the jury that it must infer the presumed fact if the [Government] proves certain predicate facts.” Francis , 471 U.S. at 314 . A mandatory presumption “violate [ s ] the Due Process Clause if [ it ] relieve [ s ] the [Government] of the burden of persuas ion on an element of an offense.” Id. In contrast, “[ a ] permissive inference suggests to the jury a possible conclusion to be drawn if the [Government] proves predicate facts, but does not require the jury to draw that

Vol. II at 30. Because it is not clear that Mr. Flechs “affirmatively approv[ed] [the instruction] at trial,” any error was not invited. Cornelius , 696 F.3d at 1319

- 15.

c. Analysis
Mr. Flechs has not shown any error was plain or affected his substantial rights. i. Plainness
Mr. Flechs reads the instruction as directing the jury to impose a mandatory presumption of intent if he “expose[d] [the] child to sexual material.” ROA, Vol. I at 43 (capitalization altered without notation). But the instruct ion provides no such clear directive. It does not mention presumption, intent, or even enticement. And to be plain, any error must be “clear or obvious” under current Supreme Court or Tenth Circuit law. United States v. Brooks , 736 F.3d 921, 930 (10th Cir. 2013) (quotations omitted). The Supreme Court and Tenth Circuit case s Mr. Flechs cites found an instruction improper only when it e xplicitly mandated a presumption. For example, he cites Sandstrom v. Montana , 442 U.S. 510 (1979), which reviewed the trial court’s instruction directing the jury that “the law presumes that a person intends the ordinary consequences of his voluntary acts. ” Id. at 512. The Supreme Court held the instruction erroneously called for a mandatory presumption because the jury was “not told that they had a choice, or that they might infer that conclusion,” but “only that the law presumed it.” Id. at 515. Mr. F lechs also cites
Patton , in which we found error when an instruction explicitly directed that “a design to effect death is inferred from the fact of killing, unless the circumstances raise a Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 2526 reasonable doubt whether such design existed.” 425 F.3d at 803 ( alterations and quotations omitted). 16 The instruction here did not exp ressly state the law “presumed” an element was satisfied when the Government proved certain predicate facts. Sandstrom , 442 U.S.
at 515. Nor did it mandate that the jury “infer[]”an element was satisfied. Patton , 425 F.3d at 803 (quotations omitted)

. Because Mr. Flechs has not shown error that was “clear[ly] or obvious[ly]” contrary to settled Supreme Court or Tenth Circuit law, he has not met his burden under plain error review

. Bro oks , 736 F.3d at 930. ii. Substantial rights
Mr. Flechs also has failed to show any error affected his substantial rights. He contends “the government could not prove its case solely with the Kik messages” because he “never proposed, suggested, intimated, requested or planned for [the minor and him] to engage in any sexual activity together.” Aplt. Br. at 45. He asserts the grooming instruction was thus essential to the Government’s case as the only way to prove
Mr. Flechs had the relevant specific intent. Id. We disagree.

16 Mr. Flechs cites other cases that similarly fall short. In Francis , the Supreme Court found an instruction was flawed because it was “cast in the language of command ” and “ carr[ied] precisely the message of the language condemned in Sandstrom .” 471 U.S. at 316. And in Wiley v. Ray l , 767 F.2d 679 (10th Cir. 1985), we relied on Sandstrom and Franklin to find the trial judge erred by instructing the jury that “[t]here is the presumption that a person intends all of the natural and probable consequences of his voluntary acts [and] [t]his presumption is overcome if you are persuaded by the evidence that the contrary is true.” Id. at 6 81 (quotations omitted). Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 2627 Mr. Flechs again misunderstands enticement. We repeat: A defendant need not desire to have sex with a minor to satisfy the intent element of § 2422(b). The statute “requires only that the defendant intend to entice a minor, not that th e defendant intend to commit the underlying sexual act.” Faust , 795 F.3d at 1249 (quotations omitted). As our discussion of the sufficiency issue shows, the Government could prove intent based on the Kik messages and Mr. Flechs’s testimony

. In addition, t he district court properly instructed the jury (1) on the meaning of enticement and (2) that a defendant can entice a minor without intending to consummate a sexual act. See ROA, Vol. I at 36, 46; see Faust , 795 F.3d at 1249. In the face of th ese instructions and the evidence, Mr. Flechs has not shown that telling the jury the “ultimate goal of grooming” is “to prepare the child for sexual activity” was prejudicial. ROA, Vol. I at 43. As discussed above, the Government introduced sufficient e vidence to prove Mr. Flechs enticed a minor even if he did not intend to consummate a sexual act with the minor. See Faust , 795 F.3d at 1249. Mr. Flechs thus has failed to show “a reasonable probability that, but for the error claimed, the result of the proceeding would have been different.” United States v. Dominguez Benitez , 542 U.S. 74, 82 (2004) (alterations and quotations omitted). Substantial Step
Mr. Flechs argues the instruction “misstated the law regarding conduct that can constitute a substanti al step” because it fail ed to require the prosecution to prove that he did more than e ngage in e xplicit sexual conversations. Aplt. Br. at 46 (quotations omitted) . Again, because he did not object to the instruction, we review for plain error. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 2728 See Booke r , 63 F.4th at 1258. He has not shown any error was plain or affected his substantial rights.

a. Plainness
A s previously noted, a n error is plain if it is “clear or obvious under current , well

settled law,” meaning “either the Supreme Court or this court [has] addressed the issue.” Brooks , 736 F.3d at 930 (quotations omitted). Mr. Flechs cites no Supreme Court case. He relies on Isabella , which said the substantial step element was met when “trial evidence showed more than e xplicit sex talk.” 918 F.3d at 835 (alterations and quotations omitted). But Isabella did not say additional evidence is always necessary to prove a substantial step. See id. at 835

Even without the grooming instruction, a jury could find Mr. Flechs took a substantial step toward enticement when , in addition to the sexually graphic and suggestive conver sations, he arranged to meet the minor and travelled to the meeting place. Mr. Flechs has not demonstrated a reasonable probability that a properly instructed jury would have found otherwise. He thus has not met his burden to show plain error. United St ates v. Bustamante

III. CONCLUSION We affirm. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 29United States v. John William Thomas Flechs , No. 22-5088 BACHARACH , J., dissenting. This case stemmed from elec tronic messages sent by Mr. John William Thomas Flechs. Mr. Flechs thought that he was messaging a 14-year-old boy named Mike . In reality, Mike was a fictional individual created by the police to catch predators. Mr. Flechs’s messages were sexually graphic, but he didn’t propose sexual activity with Mike. So the fictional Mike proposed sex. But Mr. Flechs didn’t accept. Mike then proposed sex again. And Mr. Flechs again declined to accept. Though Mr. Flechs declin ed to accept these se xual proposals, the government charged him under 18 U.S.C. § 2422(b ) with attemp t to entice a minor to engage in sexual activity. To ob tain a conviction, the government needed to pr ove that Mr. Flechs ha d attempted to obtain Mike’s assent to sex. The government couldn’t meet that burden because

 it was the fictional Mike who had proposed sex and

 it was Mr. Flechs who had declined to accept these sexual proposals. The jury found Mr . Flechs guilty anyw ay, and the majority affirms. I would reverse because the defendant never proposed a sexual activity or accepted such a proposal. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 302 1. The government needed to prove a substantial step. To obtain a convicti on, the governmen t needed to prove beyond a reasonable doubt that Mr. Flechs

 had used a means or facilit y of interstate commerce

 to knowingly attempt to persuade, induce , entice, or coerce

 an individual that he be lieved to be younger than 18

 to engage in a prohibited act involving sexual activity for which a person could be charged with a criminal offense and

 had taken a substantial step toward commission of the offense. 18 U.S.C. § 2422(b); United States v. Isabella , 918 F.3d 816, 848 (10th Cir. 2019). We must decide whether the ju ry could reasonably find a substantial step toward the comm ission of a pr ohibited act. In addressing the suff iciency of the eviden ce, we conduct de novo review. United States v. Yurek , 925 F.3d 423, 430 (10th Cir. 2019). This review entails consideration of the evid ence in the light most favorable to the government. Id. We can reverse only if no reasonable factfinder could have found guil t beyond a reasonable doubt. Id. To find gu ilt beyond a reasonable doubt, th e factfinder could rely on the evidence an d reasonable inferences drawn from that evidence, but could not engage in “speculation” or “conjecture.” United States v. Arras , 373 F.3d 1071, 1073–74 (10th Cir. 2004). Given the prohibiti on against speculation or conjecture, we can’t Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 313 “uphold a conviction . . . by pi ling inference upon inference.” United States v. Valadez-Gallegos , 162 F.3d 1256, 1262 (10th Cir. 1998).
2. There was insufficient evidence of a substantial step toward a prohibited act. From the evidence, a jury could reasonably in fer that Mr. Flechs had wanted to engage in sex with Mi ke. But § 2422(b) do esn’t criminalize wants; it criminalizes a substantial step to co mmit a prohib ited act. See 18 U.S.C. § 2422(b); United States v. Isabella , 918 F.3d 816, 831 (10th Cir. 2019). Here the prohibited act is an adul t’s sexual activity with a minor. 18 U.S.C. § 2422(b). So we must determine whether a jury could have found a substantial step to commit a prohibited act invol ving sexual activity with a minor.

a. A sexual proposal is necessary in light of the requirements for a substantial step and the acts prohibited under § 2422(b). To make that determinati on, we must consider

 what constitutes a substantial step and

 what constitutes a prohibited act.
A substantial step is “an appreciable frag ment of a crime and an action of such substantiality that, un less frustrated, the crime would have occurred.” United States v. Vigil , 523 F.3d 1258, 1267 (10th Cir. 2008) (quoting United States v. Smith , 264 F.3d 1012, 1016 (10th Cir. 2001)); see Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 324 United States v. Gordon , 710 F.3d 1124, 1151 (1 0th Cir. 2013) (“[A] substantial step is appropriately f ound where the defe ndant undertook an act adapted to, approximating, and whic h in the ordinary and likely course of things will result in, the commission of [a] particular crime.” (internal citations & quotation marks omitted)). It wouldn’t have been enough for Mr. Flechs to prepare to entice Mike; a substantial step requires conduct going beyond preparation. See Gordon , 710 F.3d at 1150 (sta ting that mere preparation does not amount to a substantial step ). The requirement of a substantial step serves to protect defendants from convictions based on “s peculative inferences.” United States v. Hernandez-Galvan , 632 F.3d 192, 198 (5th Cir. 2011) (quoting United States v. Oviedo , 525 F.2d 881, 885 (5 th Cir. 1976)). “[ U]nless and until the suspect’s behavior manifests the firm commitment to perform a criminal act, the risk is too high that we may have simply misinterpreted perfectly legal behavior, particularly when it is borne of customs, practices, or eccentricities that are not widely shared.” Hernandez-Cruz v. Holder , 651 F.3d 1094, 1103 (9th Cir. 2011); see also United States v.
Farner , 251 F.3d 510, 513 (5th Cir. 2001) (“The subs tantial step must be conduct which strong ly corroborates th e firmness of defe ndant’s criminal attempt.”). We must consider what steps ar e “substantial” based on the acts prohibited und er § 2422(b). This section prohibits persuasion , inducement , Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 335 enticement , or coercion to engage in a sexual activity. 18 U.S.C. § 2422(b). We give these terms “their ordinary meanings.” United States v. Isabella , 918 F.3d 816, 831 (10t h Cir. 2019). The ordi nary meaning of each term involves an action to overcom e another person ’s resistance. See United States v. Hite , 769 F.3d 1154, 1161 (D.C. Cir. 2014) (“The ordinary meanings of the verbs persuade, i nduce, entice, and coerce demonstrate that § 2422(b) is in tended to prohibit acts that seek to transform or overcome the will of a mi nor.”). And a person can ’t typically overcome another person’s resistance to an activity withou t proposing it. See Propose , Webster’s Third Ne w Int’l Dict. 1819 ( 1993, Philip Babcock Gove, Ph.D. ed.-in-chief) (first definition: “to form or declare a plan or intention”); Propose , Webster’s II New Riverside Dict. 944 (1994) (first definition: “To put forward for consideration, discussion, or adoption”); Proposal , Black’s Law Dict. 1474 (11th ed . 2019, Bryan A. Garner ed.-inchief) (first definition: “Something offered for consideration or acceptance; a suggestion”). Given the ordinary meaning of the four statutory terms ( persuades , induces , entices , coerces ), two circuits have used the term propose as shorthand for the conduct pr ohibited under § 2422(b). United States v. Lopez , 4 F.4th 706 (9th Cir. 2021); United States v

. Hart , 635 F.3d 850 (6th Cir. 2011). In these cases, the circuit cour ts addressed the statutory element involving persua sion, inducement, enticement, or coercion to Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 346 engage in sexual activity. Lopez , 4 F.4th at 719; Hart , 635 F.3d at 856. In both cases, the circ uit courts appeared to assu me that the four statutory terms require a proposal:

 “Section 2422(b)’s ‘s exual activity for which any person can be charged with a criminal offens e’ element requires the Government to prove the defendant proposed sexual conduct that would have constituted any criminal offense in one or more relevant jurisdictions.” Lopez , 4 F.4th at 719 (emphasis added).

 “Under § 2422(b), the governme nt must prov e that the sexual authority proposed to a minor could be charged as a criminal offense.” Hart , 635 F.3d at 856 (emphasis added).
b. Whenever we’ve upheld the sufficiency of evidence under § 2422(b), a sexual pr oposal had existed. These apparent interpretations of § 2422(b) match our own case law. Before today, we have upheld findings of a substantial step under § 2422(b) in four published opinions:
1. United States v. Faust , 795 F.3d 1243 (10th Cir. 2015)
2. United States v. Thomas , 410 F.3d 1235 (10th Cir. 2005)
3. United States v. Munro , 394 F.3d 865 (10th Cir. 2005)
4. United States v. Isabella , 918 F.3d 816 (10th Cir. 2019) In all of these cases, we upheld the convictions ba sed on the defendants’ proposals for sexu al activity. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 357 For example, in Faust , we relied on the defend ant’s discussions with the minor’s mother. 795 F. 3d at 1250. These discu ssions focuse d on the defendant’s proposal for sex with the minor. Id. Thomas was similar. There the defendan t discussed his desire for sex with a fictional 12-year- old girl. 410 F.3d at 1246. That discussion of desire constituted a proposal to engage in sexual activity “now.” Id.
Munro also involved a pr oposal for sex. There the defendant communicated with an undercover agen t posing as a 13-year-old girl. 394 F.3d at 868. The defe ndant told the fictional girl that he wanted to engage in oral sex. Id. That statement constitut ed a sexual proposal.
In Isabella , the proposal involved an adult’s request for a 14-yearold girl to send a pornographic photo of herself. 918 F.3d at 826. There the defendant sent a pho to of his penis to a 14-year-old girl and asked what she had sent. Id. The girl responded by sending a nake d photo from her neck down, and the defe ndant requested a “naugh ty” photo that included her face. Id. That request constitut ed a proposal for the girl to send child pornography, which is considered sexual activity under § 2422(b). 18 U.S.C. § 2427. 1

1 In an unpublished case, we again applied a si milar standard for a substantial step

. See United States v. Wales , 127 F. App’x 424, 431 (10th Cir. 2005) (concluding that the defendant had taken a substantial step to entice a minor by sendi ng “pornographic images to demonstrate to [a person he suspected to be a 12-year-old girl] the pose s that he wanted from her”). Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 368 In all of these cases, we relied on the defendants ’ proposals for sexual activity.

c. Sex talk alone doesn’t constitute a substantial step . We have observed that a substantial step requires “more than . .



### . explicit sex talk” with a minor. Isabella , 918 F.3d at 835 (quoting United States v. Gladish, 536 F.3d 646, 649 (7th Ci r. 2008)). The observation applies here. Mr. Flechs told gr aphic stories abou t sex during his childhood, but those storie s didn’t suffice for a substantial step

. See id.
d. The alleged grooming doesn’t support the conviction without a sexual proposal. Though sex talk alone wasn’t enough for a substantial step , the government argued to the jury that Mr. Flechs had groomed Mike for future sexual activity. The jury instructions echoed the government’s view, stating that grooming

 “refers to deliberate actions take n by a defendan t to expose a child to sexual material” and

 “can constitute a substantial step.” R. vo1. 1, at 43. The majority credits th e government’s theory of grooming , pointing out that

 we said in United States v. Faust that enticement doesn’t require an “intention to commit the underly ing sexual act” and Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 379  Isabella defined the term enticement as the arousal of “hope or desire.” Maj. Op. at 12, 14 (quoting United States v. Faust , 795 F.3d 1243, 1249 (10th Cir. 2015), and United States v. Isabella , 918 F.3d 816, 831 (10th Cir. 2019)). From th ese excerpts in Faust and Isabella , the majority concludes that a reasonable jury could have found an effort to entice Mike by arousing his hop e or desire. Maj. Op. at 12. The problem with this conclusion is that

 the undercover ag ent, posing as Mike, wa s the individual who was proposing sex with Mr. Flechs and

 Mr. Flechs never agreed to these proposals. Though Mr. Flechs never accepted Mike’s sexual proposals, the majority relies on the gr aphic nature of Mr. Flechs’s messages and trip to the skatepark. 2 But § 2422(b) isn’t violated by graphi c messages or an

2 The majority also th eorizes that a jury coul d have found that Mr. Flechs “crossed the substantial-step li ne . . . when he was driving in the minor’s neighborhood ‘again ’ and knew the minor’s guardian was away.” Maj. Op. at 17 (quo ting Suppl. R. vol. III, at 60–61). But the government didn’t present the jury with this theo ry, and it didn’t appear in the jury instructions. So we can’t affirm the conviction based on th e majority’s new theory of a substantial step : This Court has never held that the right to a jury tr ial is satisfied when an appellate court retrie s a case on appeal under different instructions and on a different theo ry than was ever presented to the jury. Appellate courts are no t permitted to affi rm convictions on any theory they please simply because the facts necessary to support the theory were presented to the jury. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 3810 arrangement to meet; th e defendant must take a substantial step to persuade, induce, entice, or coerce the minor to assent to a sexual activity.
See Part 2(a), above. Mr. Fl echs might have hoped fo r the relationship to escalate. But a substantial step involves more than hope. Mr . Flechs not only didn’t say anything to suggest a sexual encounte r, but also declined to accept any of Mike’s multip le proposals for sex. We’ve never recognized a substantial step in similar circumstances. For example, in Faust , the defendant ha d driven to the parking lot of a motel where he thought a 12- year-old girl was waiti ng. When the defendant saw a police car, he left. United States v. Faust , 795 F.3d 1243, 1246–47 (10th Cir. 2015). On app eal, the defendant challeng ed the sufficiency of the evidence und er § 2422(b), arguing that his departure from the parking lot showed that he hadn ’t intended to follow through w ith the sexual
encounter. Id. at 1248. We rejected this challenge b ecause the government hadn’t needed to prove an intent to follow through “w ith the a rrangement for a sexual encounter.” Id. We reasoned th at “§ 2422(b) requ ires only that the defendant intend to entice the minor, not that the defendant intend to

McCormick v. United States , 500 U.S. 257, 270 n.8 (1991). Even if this theory could be considered, it wouldn’t support a substantial step

. In the message, Mr. Flechs recounted dr iving in the neighborhood; but he didn’t propose sexual activity or a meeting with Mike. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 3911 commit the underlying sexual act.” Id. (quoting United States v. Thomas , 410 F.3d 1235, 1244 (10th Cir. 2005)). But there’s no suggestion in Faust that we would have upheld the conviction under § 2422(b) without th e prior arrangemen ts for a sexual
encounter. See id. After all, the me eting took place only after the defendant had arranged to have sex with the daughter. Id. at 1246. In contrast, Mr. Flechs had declined to acce pt Mike’s sexual proposals. The majority relies not only on Faust , but also on ou r statement in Isabella that enticement refers broadly to the ar ousal of hope or desire. Maj. Op. at 12–13 (quoting United States v. Isabella , 918 F.3d 816, 831 (10th Cir. 2019)). From this definition , the majority concludes that Mr. Flechs might have been trying to arouse Mike ’s hope or desire by sending graphic messages and meeting at a skatepark. Id. But “[a] postenticement act like trav el can constitute a substantial step in violating § 2422(b)” only if the tr avel “relate[s] to th e defendant’s enticing communications.” United States v. Davis , 985 F.3d 298, 305 (3d Cir. 2021). In other words, the travel must de monstrate that “the communications were not all ‘hot air.’” Id. (quoting United States v. Gladish , 536 F.3d 646, 650 (7th Cir. 2008)); see also id. at 306 (“Requiring the substantia l step to relate to th e enticing communications prevents criminalizing otherwise lawful behavior and perm itting improper inferences against a cr iminal defendant.”). Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4012 Mr. Flechs’s visit to the skatepar k doesn’t show that his graphic messages had constituted

 anything beyond “hot air” or

 an effort to obtain Mike’s assent to a sexual act. Until now, the circuits ha ve relied on personal meetings to prove a substantial step only when the defendant ha d already proposed sexual activity. See id. at 305 n.29 (collecting cases). For example, in United States v. Howard , the Fifth Circuit explained that the defendant’s conversations about sex and sendi ng of sexual photographs hadn’t constituted a substantial step . 766 F.3d 414, 426–27 (5 th Cir. 2014). The step became substantial only when the defendant discussed arrangements for sex with underage girls. Id. Our cases have upheld the finding of a substantial step only when the defendant had proposed a se xual activity before ma king arrangements to
meet. See Faust , 795 F.3d at 1250; Thomas , 410 F.3d at 1246; Munro , 394 F.3d at 869–70. Give n the absence of any pr ior proposals for sexual activity, Mr. Flechs’s trip to th e skatepark couldn’t constitute a substantial step

. The majority points to three opinions for the point that grooming could bear on the finding of a substantial step : 1. United States v. Howard , 766 F.3d 414, 425 (5th Cir. 2014) Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4113 2. United States v. Goetzke , 494 F.3d 1231, 1235–37 (9th Cir. 2007)
3. United States v. Lee , 603 F.3d 904, 904 (11th Cir. 2011) Maj. Op. at 16. But these cases also involved sexua l proposals by th e defendants, and the courts didn’t sugges t that a conviction c ould lie under § 2422(b) without a sexual proposal. In Howard , for example, the Fifth Circuit said that the defendant had crossed the line to criminality only when he told the “undercover police officer to perform sex acts on and procure birth control for [underage] girls to get them ready for him. ” 766 F.3d at 426. In Goetzke , the defendant suggest ed an exchange of pictures, expressed a desire to rub the boy’s “nic e butt,” and said that he wanted to perform oral sex on the boy. 494 F.3d at 1235. In Lee , the defendan t repeatedly expressed a desire to “co mplete the act” of sex with a child, providing details on when and how. 603 F.3d at 915. Though grooming might be pertinent, the cite d cases don’t support the finding of a substantial step without a sexual proposal. 3

3 The majority also cites United States v. Berg , noting that there the defendant didn’t dispute the sufficienc y of grooming to prove a substantial step. Maj. Op. at 18 (citing United States v. Berg , 640 F.3d 239, 246 (7th Cir. 2011)). In Berg , the defendant challenged the element of intent—not substantial step. Berg , 640 F.3d at 246, 250; see also Individual Br. and Required Short App’x of Defendant-Appellant at Pt. II, United States v. Berg , No. 09-2498 (7th Ci r. Sept. 1, 2009), available at 2009 WL 2946715 (arguing only that the government failed to prov e specific intent to engage in sexual activity with th e minor when they were to meet). The defendant Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4214 e. No other circuit has upheld a conviction under § 2422(b) without a sexual proposal. The majority states that three othe r circuits have upheld convictions under § 2422(b) based on ev idence other th an a sexual proposal, citing a Seventh Circ uit opinion, a Fourth Circu it opinion, and an unpublished Sixth Circuit opinion:
1. United States v. Hensley , 574 F.3d 384 (7th Cir. 2009)
2. United States v. Clarke , 842 F.3d 288 (4 th Cir. 2016)
3. United States v. Fox , 600 F. App’x 414 (6th Cir. 2015) (unpublished) Maj. Op. at 9–11. As th e majority acknowledges, however, all of these cases included sexual propo sals by the defendants. Maj. Op. at 11 n.8. For example, the major ity states that in Hensley , the court “[found] ‘more than enough fo r a jury to find a subs tantial step’ where the defendant ‘groom[ed] [the victim] fo r sex by conversing with her using multiple online persons,’ ‘arrange[d] a meeting place and time,’ and

‘ actually traveled to the meeting place.’” Ma j. Op. at 10–11 (quoting excerpts of Hensley with emphasis added in the majority opinion). This description suggests that Hensley upheld the finding of a substantial step without a sexual proposal. But that suggestion isn’t correct.

presumably declined to di spute the existence of a substantial step because he had told the fictiona l girl that he expected “a good blow job” and wanted to perform oral sex on her. Berg , 640 F.3d at 241–42. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4315 Hensley addressed the sufficiency of ev idence under th e plain-error standard, focusing on whether reversal was nece ssary to avoid a “manifest miscarriage of justice.” Hensley , 474 F.3d at 390. The court concluded that the finding of a substantial step didn’t involve a “man ifest miscarriage of justice” based on “transcr ipts of the conversation s” between the defendant and an undercover agent posing as a 13-year-old girl. Id. at 391. In these transcripts, the defendant learned that the girl was only 13 years old and

 told her “oh what the hell [I]’d still f*** you,”

 asked her “when she might want to have sex,”

 said “he was ‘horny’ and wanted ‘to get to know [her] with [her] clothes off,’” and

 assured the girl that she wouldn’t get pregnant if they had sex after her period or if they “e ngaged in coitus interruptus.” Id. at 387. Despite these open reques ts for sex, the majority cites this opinion as an example of a court finding “a subs tantial step based on evidence other than a proposal or acceptan ce of a proposal for sexu al activity.” Maj. Op. at 9–11. The majority is mistaken: The Seventh Circu it expressly upheld the finding of a substantial step —under the plain-error standard—based on explicit sexual proposals. The majority also relies on a Fourth Circuit case, Clarke , stating that there the court had uph eld a finding of a substantial step based on the defendant’s act of bringi ng candy to two minors. Ma j. Op. at 10 (citing Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4416 United States v. Clarke , 842 F.3d 288, 298 (4th Ci r. 2016)). In upholding the finding of a substantial step , the Fourth Circuit explained that the defendant had brought candy to the minors for “a w eekend visit with [an 8- year-old boy and 9-year -old girl] duri ng which Defenda nt hoped the children would engage in sex acts.” Clarke , 842 F.3d at 298 . But the court didn’t infer the de fendant’s “hopes” from his delivery of candy; before bringing candy, the defendan t had made it clear th at he was coming to engage in sex acts with both the boy and girl. The defendant had convey ed that intent by me ssaging an undercover officer who was posing as the father of the boy and girl. Id. at 292. When the defendant learned of the boy, the defendant re sponded: “OMG you have a son! We need to meet.” Id. (quoting Joint App’x at 98, 254). The undercover officer then as ked the defendant if he would be comfortable with the officer watchi ng the children “perform sex acts on [the d]efendant.” Id. “The defendant replied that ‘a get together would be awesome,’ and agreed to come over that weekend.” Id. (cleaned up; quoting Joint App’x at 255). The defend ant then asked the undercover officer about the children’s sexual experience and whet her the boy could get an erection and orgasm. Id. After fielding this question, the undercover officer asked the defendant if he would “play” with the girl as well as the boy. Id. The defendant replie d: “[O]f course.” Id. (quoting Joint App’x at 266). Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4517 Following these conversa tions, the defendant and undercover officer discussed their plans for a meeting where the defendant would have sex with the children. Id. The defendant instructed the undercover officer to tell the children that a “‘ good friend’ . . . would be coming to their house to engage in sex acts.” Id. (quoting Joint App’x at 117, 272). On the day of the planned meeting, the defendant asked the undercover officer if it would be okay to perform oral sex on the boy and girl. Id. These facts show numerous sexual proposals befo re the planned meeting. But the majority cites Clarke as an example of a circuit court finding “a substantial step based on evidence other than a proposal or acceptance of a proposal for sexual activity.” Maj. Op. at 9–10 . I respectfully disagree with this characterization: The Four th Circuit upheld the finding of a substantial step based on explicit sexual proposals. Finally, the majority relies on an unpublished Si xth Circuit opinion,
Fox , stating that there the court upheld a finding of substantial step based solely on flattery and purchase of expensive gift s. Maj. Op. at 11. There an underage girl testified th at the defendant had “pic ked her up” at night and “revealed [his] favor: he wanted to have intercourse with her because, in [the girl’s] words, ‘he was going to jail for a re ally long time and he didn’t know if he was going to ever get it again.’” Fox , 600 F. App’x at 417 Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4618 (quoting R. at 159). The request for intercourse constituted a sexual proposal. 4 In each of the cited opin ions, the circuit court upheld the finding of a substantial step based on the defendan t’s sexual proposals.
f. A substantial step can’t be based on the combination of graphic stories and trip to the skatepark. Despite the presence of a sexual pr oposal in all of these cases, the majority relies on the combination of Mr. Flechs’s graphic stories and trip to the skatepark. For two reasons, the graphic stories and trip to the skatepark don’t substitute for a sexual proposal. First, the combination of graphic stories and trip to the skatepark don’t show a firm commit ment to persuade, induce, entice, or coerce Mike.
See Part 2(a), above. Second, without requir ing a sexual proposal, we are inviting future juries to speculate from “perfectly legal behavior ” about the firmness of a defendant’s intent to commit a criminal act. See Part 2(a), above; see also

4 The majority also cites a st atement from the Sixth Circuit’s unpublished opinion: “That evidence of sexually explic it online or telephone conversations sufficed to convict other defendants under § 2422(b) does not mean that such evidence is necessary to prove attempted enticement or coercion.” Fox , 600 F. App’x at 418 (quoted in Maj. Op. at 8 n.6). The majority states that it finds the Si xth Circuit’s reasoning for this statement “instructive .” Maj. Op. at 8 n.6. But the Sixth Circuit provided no reasoning for this statement. See Fox , 600 F. App’x at 418. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4719 United States v. Leos–Quijada , 107 F.3d 786, 794 (10t h Cir.1997) (stating that the eviden ce supporting a guilty verdict mu st raise more than the mere suspicion of guilt, and the jury’s inferences must be “more than speculation and conjecture in order to be reasonable”). Mr. Flechs indisputably engaged in egregious sex talk with someone that he thought was only 14-years-old. But we’ve he ld that sex talk isn’t enough to convict under § 2422(b). United States v. Isabella , 918 F.3d 816, 835 (10th Cir. 2019); see Part 2(c), above. Withou t a sexual proposal, how will we safeguard agai nst speculation from sex talk alone? The majority theorizes that the trip to a skatepark could constitute an effort to entice Mike into a sexual act. That’s po ssible, but this theory rests on speculation because the trip itself didn’t suggest an effort to entice Mike to do anything. For both reasons, the graphic stories and trip to the skatepark can’t
create a substantial step without Mr. Flechs’s maki ng or accepting a sexual proposal.
g. The statutory language contro ls but doesn’t require magic words. The majority calls my approach a “strict proposal requirement,” suggesting that it would allow child predators to avoid criminal responsibility “by carefully avoiding direct requests for sex.” Maj. Op. at 11. I respectfully disagree. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4820 We’re bound by the langu age that Congress us ed, and that language criminalizes a substantial step to persuade, induce, en tice, or coerce a minor to engage in a sexual activity. 18 U. S.C. § 2422(b); see Part 2(a), above. In applying this statutory language, we mu st determine whether the defendant’s conduct “manif ests the firm commitment to perform a criminal
act.” Hernandez-Cruz v. Holder , 651 F.3d 1094, 1103 (9th Cir. 2011); see Parts 2(a), above.
A firm commitment may exist when the defe ndant propose s sexual activity to a minor. Without a sexual proposal, we would need to enter the realm of speculation about a defend ant’s further desi gns and blur the boundary between preparation and a fi rm commitment to criminality. Although a sexual propo sal is required, this requirement doesn’t permit “subtle manipulation.” See Maj. Op. at 11. A sexual proposal or assent to a sexual proposa l could exist in many fo rms, and the law doesn’t provide a catalog of t hose forms. But the law does require conduct manifesting a firm commitment to persuade, induce, entice, or coerce a minor to engage in sexual activity; and that requirement necessarily entails a sexual proposal of some sort. 5

5 The majority theori zes that Mr. Flechs’s gr aphic messages might have constituted an implic it proposal for a sexual act with Mike. Maj. Op. at 19 n.13. But the government doesn’t assert this theory on appeal, and we generally consider it “imprudent” to a ffirm on a theory that the appellee hasn’t advanced. United States v. Woodard , 5 F.4th 1148, 1154 (10th Cir. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 4921 * * * The majority upholds the conviction under § 2422(b) without the defendant’s making or accepting a sexual propos al. In doing so, the majority disregards the need for conduct showing a firm commitment to persuade, induce, entice, or coerce a minor to assent to a sexual activity. By loosening these requirements, th e majority muddies the line between explicit sex talk and a substantial step. See United States v. Gladish , 536 F.3d 646, 650 (7 th Cir. 2008) (“Treating spee ch (even obscene speech) as the ‘substantial step’ would abolish any requir ement of a substantial step.”). I would instead retain that line and continue to require a firm commitment to persuade , induce, entice, or co erce a minor through a proposal for sexu al activity.

2021); United States v. Chavez , 976 F.3d 1178, 1203 n.17 (10th Cir. 2021). So we need not decide whether Mr. Flechs made an implicit proposal. Appellate Case: 22-5088 Document: 010111034849 Date Filed: 04/19/2024 Page: 50
