The Commission, Stonewalled.

"There could have been absolutely no doubt in the mind of anyone at the C.I.A. -- or the White House -- of the commission’s interest in any and all information related to Qaeda detainees involved in the 9/11 plot. Yet no one in the administration ever told the commission of the existence of videotapes of detainee interrogations." From a few days ago, 9/11 Commission Chairs Thomas Kean and Lee Hamilton angrily accuse the CIA and Dubya White House of stonewalling their investigation. "As a legal matter, it is not up to us to examine the C.I.A.’s failure to disclose the existence of these tapes. That is for others. What we do know is that government officials decided not to inform a lawfully constituted body, created by Congress and the president, to investigate one the greatest tragedies to confront this country. We call that obstruction."
