AP: Libby resigns
Libby submitted his resignation to White House chief of staff Andy Card. It was accepted and Libby left the White House. Card notified Bush.

The indictment alleges that Libby began digging for details about Joseph Wilson, Plame's husband and an Iraq war critic, well before the former ambassador went public July 6, 2003, in a newspaper opinion piece with his criticism of the Bush administration's use of faulty prewar intelligence on Iraq's nuclear ambitions.

Libby made his first inquiries about Wilson's travel to Niger in late May 2003 - a trip the government sent him on in early 2002 to check on reports that Saddam was trying to buy uranium - and by June 11 Libby was informed by a CIA official that Wilson's wife worked for the agency and might have sent Wilson on the trip.

On June 12, 2003, the indictment alleges, Libby heard directly from Cheney that Plame worked for the spy agency.

"Libby was advised by the vice president of the United States that Wilson's wife worked at the CIA in the counterproliferation division. Libby understood that the vice president had learned this information from the CIA," Fitzgerald said in a news release.

A short time later, Libby began reaching out to reporters, starting with The New York Times' Judith Miller on June 23.
