Cheney could have been the direct source of the leak and simply be so delusional he himself doesn't think so.
Cheney Reportedly Interviewed in Leak of C.I.A. Officer's Name
By DAVID JOHNSTON
WASHINGTON, June 4 — Vice President Dick Cheney was recently interviewed by federal prosecutors who asked whether he knew of anyone at the White House who had improperly disclosed the identity of an undercover C.I.A. officer, people who have been involved in official discussions about the case said on Friday.
Mr. Cheney was also asked about conversations with senior aides, including his chief of staff, I. Lewis Libby, according to people officially informed about the case. In addition, those people said, Mr. Cheney was asked whether he knew of any concerted effort by White House aides to name the officer. It was not clear how Mr. Cheney responded to the prosecutors' questions.
The interview of the vice president was part of a grand jury investigation into whether anyone at the White House violated a federal law that makes it a crime to divulge the name of an undercover officer intentionally.
Mr. Cheney is not thought to be a focus of the inquiry, which Patrick J. Fitzgerald, the United States attorney in Chicago, heads. Mr. Fitzgerald was appointed by the Justice Department as a special counsel in the case.
