Appealing the judgment in a criminal case, Rodrick Rochelle Monroe raises arguments that he concedes are foreclosed by United States v. Betancourt, 586 F.3d 303, 308-09 (5th Cir. 2009), which reaffirmed the holding in United States v. GamezGonzalez, 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.
