Appealing the Judgment in a Criminal Case, Clinton Jennings raises arguments that are foreclosed by United States v. Burns, 433 F.3d 442, 450-51 (5th Cir. 2005), which held that an otherwise valid appeal waiver is not rendered invalid, or inapplicable to an appeal seeking to raise an error pursuant to United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), merely because the waiver was made before Booker. Jennings also raises arguments that are foreclosed by United States v. Austin, 432 F.3d 598, 599-600 (5th Cir. 2005), which held that the application of Booker’s remedial opinion to a sentencing hearing where the underlying offense was committed pre-Booker does not violate constitutional due process or ex post facto requirements. The Government’s motion for summary affirmance is GRANTED, and the judgment of the district court is AFFIRMED.
