PER CURIAM:

Justin Michael Isaac appeals his conviction and 168-month sentence imposed 

following his guilty plea to conspiracy to distribute and possess with intent to distribute 5

kilograms or more of cocaine and 400 grams or more of fentanyl, in violation of 21 U.S.C. 

§§ 841(a)(1), (b)(1)(A), 846. The Government moves to dismiss the appeal based on the 

appeal waiver contained in Isaac’s plea agreement, pursuant to which Isaac agreed to waive 

his right to appeal any sentence within the statutory maximum. Isaac’s counsel has filed a 

response pursuant to Anders v. California, 386 U.S. 738 (1967), stating that there are no 

meritorious grounds for appeal but questioning the validity of Isaac’s guilty plea. Isaac

has filed a pro se supplemental brief, claiming that he was promised a lower sentence and 

that the drug weight used for calculating his Sentencing Guidelines range unfairly included 

conduct for which he was not charged. We affirm in part and dismiss in part.

Initially, an appeal waiver does not prevent a defendant from challenging the 

validity of his guilty plea. United States v. McCoy, 895 F.3d 358, 364 (4th Cir. 2018). 

Before accepting a guilty plea, the district court must conduct a plea colloquy in which it 

informs the defendant of, and determines he understands, the rights he is relinquishing by 

pleading guilty, the charge to which he is pleading, and the maximum and mandatory 

minimum penalties he faces. Fed. R. Crim. P. 11(b)(1); United States v. DeFusco, 949 

F.2d 114, 116 (4th Cir. 1991). The court also must ensure that the plea is voluntary and 

not the result of threats, force, or promises not contained in the plea agreement, Fed. R. 

Crim. P. 11(b)(2), and “that there is a factual basis for the plea,” Fed. R. Crim. P. 11(b)(3). 

Because Isaac did not move to withdraw his plea in the district court, we review the

adequacy of the plea colloquy for plain error. United States v. Williams, 811 F.3d 621, 622 

(4th Cir. 2016).

In his pro se brief, Isaac appears to argue that his guilty plea was induced by a 

promise—not contained in the plea agreement—that he would receive a sentence of no 

more than 10 years. However, Isaac identifies nothing in the record to substantiate this 

claim. Moreover, at the Rule 11 hearing, Isaac confirmed his understanding that he could 

receive a sentence of up to life imprisonment and that his plea was not the result of threats 

or outside promises. For these reasons, and based on our independent review of the record, 

we conclude that Isaac’s guilty plea was knowing, voluntary, and supported by an 

independent basis in fact.

Turning to the appeal waiver, we review the validity of an appellate waiver de novo 

and “will enforce the waiver if it is valid and the issue appealed is within the scope of the 

waiver.” United States v. Adams, 814 F.3d 178, 182 (4th Cir. 2016). A waiver is valid if 

it is “knowing and voluntary.” Id. To determine whether a waiver is knowing and 

voluntary, “we consider the totality of the circumstances, including the experience and 

conduct of the defendant, his educational background, and his knowledge of the plea 

agreement and its terms.” McCoy, 895 F.3d at 362 (internal quotation marks omitted). 

“Generally . . . , if a district court questions a defendant regarding the waiver of appellate 

rights during the Rule 11 colloquy and the record indicates that the defendant understood 

the full significance of the waiver, the waiver is valid.” Id. (internal quotation marks 

omitted). Our review of the record confirms that Isaac knowingly and voluntarily waived 

his right to appeal. We therefore conclude that the waiver is valid.

Even so, we will not enforce a valid appeal waiver if the Government breached its 

obligations under the plea agreement. United States v. Lewis, 633 F.3d 262, 271 n.8 

(4th Cir. 2011). In his pro se brief, Isaac appears to claim that his plea agreement was 

materially breached because the drug weight used for his Guidelines calculation included 

a controlled substance that was not part of the charge to which he pled guilty. However, 

nothing in the plea agreement prohibited the district court from considering relevant but 

uncharged conduct, and, moreover, the magistrate judge clearly confirmed Isaac’s 

understanding that his sentence could be based on more than just the minimum conduct 

necessary to establish the charged offense. Thus, we reject Isaac’s argument.

In accordance with Anders, we have reviewed the entire record in this case and have 

found no meritorious grounds for appeal that fall outside of the scope of the waiver. 

Accordingly, we grant the Government’s motion to dismiss as to those issues falling within 

the waiver’s scope, and we affirm the remainder of the district court’s judgment. This court 

requires that counsel inform Isaac, in writing, of the right to petition the Supreme Court of 

the United States for further review. If Isaac requests that a petition be filed, but counsel 

believes that such a petition would be frivolous, then counsel may move in this court for 

leave to withdraw from representation. Counsel’s motion must state that a copy thereof 

was served on Isaac.

We dispense with oral argument because the facts and legal contentions are 

adequately presented in the materials before this court and argument would not aid the 

decisional process.
