ANDREA MITCHELL, MSNBC: Benghazi. You wrote in the book that you disagreed with David Petraeus, your successor, who immediately after the fact told the situation room he thought it was a spontaneous demonstration outside the consulate that night. Why did you disagree at the time? What didn't ring true about that?
LEON PANETTA: I didn't have any specific information, but the fact was that when you bring grenade launchers to a demonstration, there's something else is going on. From the very beginning I sensed that this was an attack, a terrorist attack on our compound. I remember saying to him look, based on the weapons that I see and the nature of the attack, I think this was a terrorist attack. He said look, the information we are getting from intelligence sources is that it really was a demonstration. I said you know, David, I don't see it that way. I think we are dealing with what in effect, with a group of terrorists who took advantage of the situation in order to go after our people.
