WOLF BLITZER (HOST): Let me quickly get your thoughts on your investigation into happened in Benghazi, Libya. All of us remember the 11 hours of testimony that Hillary Clinton, the former secretary of state, provided in open session. You're now having these closed door meetings with others who were involved. The former CIA Director General Petraeus testified yesterday. Leon Panetta, the former defense secretary, will testify tomorrow. Are you making any headway, are you learning new information about what may have happened?

REP. TREY GOWDY (R-SC): Yes, sir, we're actually doing an interview today with a witness named Charlene Lamb. We are up to our sixty-sixth witness interview, the overwhelming majority of which have never been talked to by any congressional committee before. And you're right, Secretary Clinton was in public. But it's the only one that's been in public, and it's the only one that's going to be in public because the private transcribed interviews are so much more effective for gathering information than a public spectacle. So, all the rest of them are going to be in private, and all the rest of them will be productive.
