President Bush, Iraq, and WMD

Did President Bush ever say the United States has definitive evidence or proof that Iraq has weapons of mass destruction?

Bush Speech to the United Nations (Sep 12, 2002)

U.S. reluctant to reveal data (January 27, 2003)

I don`t recall the words “proof” or “definitive evidence” ever being used by the President. That would be the key to the OP.
