Ha ha.

As the investigation into the leak of a CIA agent's name hurtles to an apparent conclusion, special prosecutor Patrick J. Fitzgerald has zeroed in on the role of Vice President Cheney's office, according to lawyers familiar with the case and government officials. The prosecutor has assembled evidence that shows Cheney's long-running feud with the CIA contributed to the unmasking of operative Valerie Plame.

In grand jury sessions, including with New York Times reporter Judith Miller, Fitzgerald has pressed witnesses on what Cheney may have known about the effort to push back against ex-diplomat and Iraq war critic Joseph C. Wilson IV, including the leak of his wife's position at the CIA, Miller and others said. But Fitzgerald has focused more on the role of Cheney's top aides, including Chief of Staff I. Lewis "Scooter" Libby, lawyers involved in the case said.

One former CIA official told prosecutors early in the probe about efforts by Cheney's office and his allies at the National Security Council to obtain information about Wilson's trip as long as two months before Plame was unmasked in July 2003, according to a person familiar with the account.
