Richard Clarke will testify today before the Commission on 9/11 . Here's an open thread to discuss it.

Clarke, who is to testify today before the independent commission looking into the attacks, said in a telephone interview that CIA Director George J. Tenet used his morning briefings to warn Bush "over and over" beginning in June 2001 that al Qaeda would "almost certainly" stage a major attack. Clarke said the CIA believed it was "most likely" to occur overseas. "Virtually every day, George Tenet said to him: There's an impending al Qaeda attack," Clarke said. "You know the old Shakespearean line -- I think they doth protest too much. They're guilty of not having done enough."
