RATIGAN: How far back do you think is appropriate? Because the one thing that's not on this list would be, for instance, a torture investigation.

CHAFFETZ: Well, it may be on the list as well. I'm not afraid of going after the Bush administration. I wasn't brought here by the establishment. When I ran for congressman in 2008, I'm just a freshman year, George W. Bush, Orrin Hatch, and Bob Bennett, three Republicans, they campaigned against me. So I don't mind going back and looking at 'em. So I don't have any hesitation there whatsoever.
