I'd recommend that you look directly at Staff Statement No. 15 when discussing the Iraq-al Qaeda issue, specifically regarding the Commissions' hearing today. Note that the paragraph in question is on page 5 of the attached statement. I'd point out that it is but one paragraph in a 12-page statement. The AP and others have picked up on one sentence, which was carefully worded: "We have no credible evidence that Iraq and al Qaeda cooperated on attacks against the United States."
The rest of the paragraph concisely summarizes the cases where we can identify cooperation and other connections where they exist.
The other relevant information is included on page 8 of Staff Statement No. 16. In the statement, which exhaustively discusses the 9-11 plot, we address the movements of the hijackers in the years leading up to the attacks. This paragraph addresses reports that Mohammed Atta met with an Iraqi intelligence agency in Prague on April 9, 2001.
Mr. Reynolds supplies a link to the staff statements in question.
