Appealing the judgment in a criminal case, Jesus Hernán De La Paz raises an argument that is foreclosed by United States v. Betancourt, 586 F.3d 303, 308-09 (5th Cir. 2009), which held that knowledge of drug type and quantity is not an element of a 21 U.S.C. § 841 offense. Accordingly, the motion for summary disposi *333 tion is GRANTED, and the judgment of the district court is AFFIRMED.
