The Italian government's intelligence agency obtains documents that appear to show that Iraqi officials attempted to buy yellowcake, a substance that can be enriched to produce weapons-grade uranium, from the African nation Niger. The evidence is shared with British and U.S. intelligence.
2002
February: The CIA, in response to concerns raised by Vice President Cheney's office, looks into British reports that Iraq tried to buy uranium from Africa. CIA officials dispatch ex-diplomat Joseph Wilson to Niger to investigate.
March: After an eight-day trip to Africa, Wilson reports to the CIA that he believes the allegations are "bogus." The agency sends a March 9 memo to the White House summarizing Wilson's findings.
Oct. 10-11: Both the House and the Senate pass resolutions authorizing the use of force against Iraq. Many members of Congress mention the specter of an Iraqi nuclear threat as a reason; several Senators cite as especially persuasive the British intelligence report claiming Iraq sought uranium from Africa.
