Appealing the judgment in a criminal case, Julio Cesar Parrales-Zuniga raises an argument that he concedes is foreclosed by United States v. Betancourt, 586 F.3d 303, 308-09 (5th Cir. 2009), which reaffirmed the holding in United States v. Gamez-Gonzalez, 319 F.3d 695, 700 (5th Cir. 2003), that knowledge of drug type and quantity is not an element of the offense under 21 U.S.C. § 841. The appellant’s motion for summary disposition is GRANTED, and the judgment of the district court is AFFIRMED.
