Cheney Involved with Leak?

Bloomberg reports this morning that special prosecutor Patrick Fitzgerald may be "focusing on whether Vice President Dick Cheney played a role in leaking a covert CIA agent's name, according to people familiar with the probe that already threatens top White House aides Karl Rove and Lewis Libby." Fitzgerald has interviewed several current and former top Cheney aides, and the Bloomberg pieces notes that Judy Miller wrote in her first-person piece yesterday that the prosecutor asked her if Cheney knew was Libby "was doing and saying" concerning the Wilson-Plame affair.

The plot thickens.
