What's kind of sad is that he was at the bottom of this before it happened. He talked about the information he got from LIWA for his 1999 trip to Russia, information that the CIA couldn't provide. That was his first clue that our intelligence structure was dysfunctional. Or maybe that was his second clue since by 1999 he surely knew that the man in the Oval Office was doing little to mount a serious response to the growing threat of terrorism.
It must really hurt him to know this could have been stopped.
It was interesting watching his face, especially during the last witness, Dugan. A lot of shaking of the head.
