Ron Paul says he has to “expose” Gingrich “for what he’s been doing all these years” (audio)

I asked Ron Paul a question as Paul walked out of the room just now (after addressing employees of Principal Financial in Des Moines). “You’ve been fairly aggressive in your criticism of Congressman Gingrich lately, in terms of your campaign ads,” I said.

“Who’s that? Who is that?  Oh, that guy who used to be the speaker?” Paul said, with a grin on his face.  “I have to expose him for what he’s been doing all these years. That’s all we’re doing, trying to present the facts.”
