Bush asked Richard A. Clark "See if Saddam did this"

According to Richard A. Clarke, a former National Security Council Official: "On September 12th, I left the video conferencing center and there, wandering alone around the situation room, was the president. He looked like he wanted something to do. He grabbed a few of us and closed the door to the conference room. "Look," he told us, "I know you have a lot to do and all, but I want you, as soon as you can, to go back over everything, everything. See if Saddam did this. See if he's linked in any way."
