Dondell Pea appeals the 240-month mandatory minimum sentence imposed following his guilty plea conviction of possession with intent to distribute 50 grams or more of methamphetamine. He argues that his sentence violates the Eighth Amendment’s prohibition against cruel and unusual punishment because it is grossly disproportionate to his offense and because the mandatory minimum was enhanced based on a purportedly insignificant prior conviction for a felony drug offense.

Reviewing this preserved issue de novo, we find no constitutional error. United States v. Mills, 843 F.3d 210, 217 (5th Cir. 2016), cert. denied, — U.S. -, 137 S.Ct. 1601, 197 L.Ed.2d 726 (2017). Pea’s 240-month sentence was not grossly disproportionate to the severity of his controlled substance offense. See Mills, 843 F.3d at 217; United States v. Helm, 502 F.3d 366, 368 (5th Cir. 2007). Accordingly, the 240-month sentence was not unconstitutionally cruel and unusual, regardless of the fact that it was the mandatory minimum sentence. See Harmelin v. Michigan, 501 U.S. 957, 995, 111 S.Ct. 2680, 115 L.Ed.2d 836 (1991).

AFFIRMED.
