Gerardo Lievanos appeals his guilty-plea conviction of possession with intent to distribute more than 500 grams of cocaine. Lievanos argues, for the first time on appeal, that the district court lacked jurisdiction to convict and sentence him because 21 U.S.C. § 841 is unconstitutional under Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). Lievanos correctly concedes that his arguments are foreclosed by our opinion in United States v. Slaughter, 238 F.3d 580, 582 (5th Cir. 2000). He raises the issue to preserve it for further review.

AFFIRMED.
