Here is an internal 9/11 Commission e-mail from staffer Warren Bass calling a claim by White House press spokesman Scott McClellan that the administration was co-operating fully "flatly untrue." Thank you to Kevin Fenton of www.historycommons.org for showing this to me. The source link is blurry. I have uploaded the downloaded/clear version for you to download.

Several of this week's new entries focus on the 9/11 Commission, in particular its Executive Director Philip Zelikow, who offered public support for the invasion of Iraq in 2002, but did not want the commission to investigate false claims of links between 9/11 and Iraq. After the commission's investigation started, one staffer was sent to review CIA documents, and another, Warren Bass, was sent to review NSC material. Bass came to favor the account of events in the Bush Administration in the summer of 2001 given by counterterrorism "tsar" Richard Clarke over that given by National Security Advisor Condoleezza Rice. However, Zelikow distrusted Clarke and tried to protect his friend Rice; it was these ties to Rice which caused both Bass and Commissioner Bob Kerrey to threaten to quit the commission, although neither of them made good on their threat.
