PER CURIAM: *

Donna Forbes appeals the mandatory life sentence imposed following her guilty plea to a single court of first-degree murder on a government reservation. She raises constitutional challenges to her sentence. Although we usually review such constitutional claims *de novo, United States v. Romero-Cruz,*201 F.3d 374, 377 (5th Cir.2000), we review them for plain error in this instance because Forbes did not raise them in the district court, *see United States v. Howard,*220 F.3d 645, 647 (5th Cir.2000).

Forbes asserts that her confinement to a mandatory life sentence is “cruel and unusual punishment” in violation of the Eighth Amendment, because the harshness of the sentence is grossly disproportionate to the gravity of her offense. In determining whether a sentence is “grossly disproportionate,” we look to *Rummel v. Estelle,*445 U.S. 263, 100 S.Ct. 1133, 63 L.Ed.2d 382 (1980), as a benchmark. *United States v. Gonzales,*121 F.3d 928, 943 (5th Cir.1997). Measured against the *Rummel*standard, Forbes’s mandatory life sentence for first-degree murder is not grossly disproportionate. *See Smallwood v. Johnson,*73 F.3d 1343, 1347 (5th Cir.1996). Moreover, Forbes’s inability to present mitigating evidence does not render her sentence cruel and unusual. *See Harmelin v. Michigan,*501 U.S. 957, 994-96, 111 S.Ct. 2680, 115 L.Ed.2d 836 (1991).

Forbes argues that her mandatory life sentence violates the Equal Protection Clause because it causes her to be treated differently from defendants not facing a mandatory life sentence and fails to serve a legitimate governmental objective. The rational basis test applies to Forbes’s claim, because the statute under which she was sentenced, 18 U.S.C. § 1111(b), neither classifies persons by suspect classes nor classifies in such a way as to impair the exercise of a fundamental right. *See Rublee v. Fleming,*160 F.3d 213, 217 (5th Cir.1998). Forbes has failed to show that she has been treated differently from a similarly situated group of defendants or that Congress’s prescription of a mandatory life sentence for first-degree murder is not rationally related to a legitimate governmental interest. *See id.*

Forbes avers that her mandatory life sentence contravenes the Due Process Clause because she was precluded from receiving an individualized sentence that adequately considered her particular circumstances. The Constitution does not *326guarantee individualized sentencing or provide for the presentation of mitigating evidence in noncapital cases. *See Harmelin,*501 U.S. at 995, 111 S.Ct. 2680. Thus, there is no constitutional impediment to the district court’s imposing a mandatory sentence without considering Forbes’s particular circumstances. *See, e.g., United States v. White,*869 F.2d 822, 825 (5th Cir.1989).

Forbes urges that her mandatory life sentence violates the Separation of Powers doctrine because the prosecutor has the sole power to charge an offense that carries a mandatory minimum sentence. Forbes thus asserts that the power of the Executive Branch is increased at the expense of the Judiciary. “The scope of judicial discretion with respect to sentencing is subject to Congressional control,” and Congress can constitutionally eliminate all discretion in sentencing judges by establishing mandatory sentences. *Mistretta v. United States,*488 U.S. 361, 364, 109 S.Ct. 647, 102 L.Ed.2d 714 (1989). Thus, to the extent that the decision to charge crimes carrying mandatory minimum sentences allows the Executive Branch to exercise some control over a sentence, that control derives from legislative decisions that are within Congress’s authority. *Id.; Chapman v. United States,*500 U.S. 453, 467, 111 S.Ct. 1919, 114 L.Ed.2d 524 (1991).

The judgment is AFFIRMED. The government’s motion for summary affirmance is GRANTED. The Government’s alternative motion for an extension of time to file its brief is DENIED as unnecessary.
