Task: Wrong Candidate Generation
Input (English): did not present any evidence before the district court to meet his burden of showing that the affidavit, which directly corroborates Johnson’s testimony before the magistrate judge, is false or unreliable. Accordingly, even assuming arguendo that the district court erred, we readily conclude that any error was harmless. B. Credibility of Witnesses The district court’s findings of fact at a revocation hearing are reviewed for clear error. United States v. Almand, 992 F.2d 316, 318 (11th Cir.1993). “The credibility of a witness is in the province of the factfinder and this court will not ordinarily review the factfinder’s determination of credibility.” United States v. Copeland, 20 F.3d 412, 413 (11th Cir.1994); see also United States v. Ramirez-Chilel, 289 F.3d 744, 749 (11th Cir.2002) (<HOLDING>). We defer to the lower court’s credibility
