Zelikow dissed Clarke

Think Progress: Zelikow 'made it clear' to 9/11 Commission that Richard Clarke 'Should Not Be Believed':

"9/11 Commission staff director Philip Zelikow was not interested in pursuing criticisms against Rice. Zelikow — who had worked closely with Rice on the Bush transition team in 2000 and 2001 — “made it clear to the team’s investigators that Clarke should not be believed, that his testimony would be suspect.”"
