Vice President Cheney and his then-Chief of Staff I. Lewis "Scooter" Libby were personally informed in June 2003 that the CIA no longer considered credible the allegations that Saddam Hussein had attempted to procure uranium from the African nation of Niger, according to government records and interviews with current and former officials. The new CIA assessment came just as Libby and other senior administration officials were embarking on an effort to discredit an administration critic who had also been saying that the allegations were untrue.
CIA analysts wrote then-CIA Director George Tenet in a highly classified memo on June 17, 2003, "We no longer believe there is sufficient" credible information to "conclude that Iraq pursued uranium from abroad." The memo was titled: "In Response to Your Questions for Our Current Assessment and Additional Details on Iraq's Alleged Pursuits of Uranium From Abroad."
Despite the CIA's findings, Libby attempted to discredit former Ambassador Joseph Wilson, who had been sent on a CIA-sponsored mission to Niger the previous year to investigate the claims, which he concluded were baseless.
