The district court essentially made a credibility determination in choosing to believe Tran’s statement to the agents about Tinh. See United States v. Shipley, 963 F.2d 56, 59 (5th Cir.1992) (<HOLDING>). Furthermore, it is certainly plausible that

C: holding that when the testimony relating each of the statements by codefendants was admissible against at least one of the codefendants the statements were not rendered inadmissible because each statement would be hearsay as to the other two defendants
D: holding that pretext is subject to the clearly erroneous standard
