The most general allegations of impersonation of a government official sufficiently charge this element of the offense. Failure to prove that the representation of federal authority was false is reversible error. United States v. McNaugh, 42 F.2d 835, 836-37 (2d Cir. 1930). Proof of the falsity of the representation can be made by a properly authenticated affidavit of the person having custody of the personnel records of the assumed office reciting that a diligent search reveals no record of defendant's employment. T'Kach v. United States, 242 F.2d 937, 937-38 (5th Cir. 1957).
