should not be credited. This argument fails. "It is the province of the jury and not of the court to determine whether a witness who may have been inaccurate, contradictory and even untruthful in some respects was nonetheless entirely credible in the essentials of his testimony." United States v. O'Connor, 650 F.3d 839, 855 (2d Cir. 2011) (internal quotations marks omitted). Appellant has provided no reason for us to second guess the credibility determinations of the jury, especially where, as here, the cooperating witnesses testified about their agreements with the Government and the impact that lying would have on those agreements.
