Cheney denies outing CIA agent

WASHINGTON, Oct. 31 (UPI) -- Former U.S. Vice President Dick Cheney told a special investigator he didn't reveal the identity of a covert CIA agent, FBI documents show.

Documents from the May 8, 2004, interview were released Friday by the FBI after a lawsuit from Citizens for Responsibility and Ethics in Washington, a non-profit group.

Cheney's denial of any role in the outing of CIA agent Valerie Wilson appeared to conflict with the 2007 testimony of his chief of staff, I. Lewis Libby Jr., who was convicted of perjury and obstruction of justice, The New York Times reported Saturday. Libby's sentence was commuted by then President George W. Bush.

During the interview, Cheney said he could not remember how or when he learned of Wilson's identity and could not remember discussing it with Libby or other White House officials, The Washington Post reported Saturday.

The White House leak about Wilson's identify embarrassed Bush and Cheney, whose role has been a mystery, The Post reported.
