Sure, and Chris Matthews (or any other lefty in the media) wouldn't have already challenged his claim. Say it: D E N I A L.Oh yeah, he made the whole thing up, right? Claims he was audited by the IRS and Obama just let it slide. Deny much?He made a claim. It has not been confirmed.
He made a claim, and did not back it up with any paper evidence.
He could just as easily have brought the audit forms with him on to the show. If the IRS audited him, this means they left a paper trail that he can easily produce. It's that simple.
