The members of Mike Hurley's [9/11 Commisson investigative] team were ... alarmed by the revelations, week by week, month by month, of how close the commission's chief director, Philip Zelikow, was to Rice and others at the White House. They learned early on about Zelikow's work on the Bush transition team in 2000 and early 2001, and about how much antipathy there was between him and [Counterterrorism Czar"] Richard Clarke. They heard the stories about Zelikow's role in developing the "pre-emptive war" strategy at the White House in 2002. Zelikow's friendships with Rice and others were a particular problem for Warren Bass, since Rice and Clarke were at the heart of his part of the investigation. It was clear to some members of team that they could not have an open discussion in front of Zelikow about Rice and her performance as National Security Adviser. For Hurley's team, there was a reverse problem with Clarke. It was easy to talk about Clarke in Zelikow's presence, as long as the conversation centred on Clarke's failings at the NSC and his purported dishonesty. Long before Bass had seen Clarke's files, Zelikow made it clear to the team's investigators that Clarke should not be believed, that his testimony would be suspect. He argued that Clarke was a braggart who would try to rewrite history to justify his errors and slander his enemies, Rice in particular.
