To be totally non biased about this it is clear in looking at the Wilson statements since he returned from Niger and checking them against the committee reports and the CIA statements that Wilson has lied numerous times. The question is WHY?
By the way, Fitzgerald's investigation revealed that Cheney knew about Wilson far earlier than he's claimed...although I continue to believe that Cheney played no part in selecting Wilson and never saw or heard of his report until much after it was submitted.
