Appealing the judgment in a criminal case, Rafael Ramirez-Perez raises arguments that he concedes are foreclosed by United States v. Gomez-Herrera, 523 F.3d 554, 562-63 (5th Cir. 2008), which rejected the argument that the existence of fast track programs in some districts and not in others creates unwarranted sentencing disparities within the meaning of 18 U.S.C. § 3553(a)(6). The Government’s motion for summary affirmance is GRANTED, its alternative motion for an extension of time to file a brief is DENIED, and the judgment of the district court is AFFIRMED.
