Per Think Progress:
Lewis “Scooter’’ Libby, Vice President Dick Cheney’s chief of staff, told special prosecutor Patrick Fitzgerald that he first learned from NBC News reporter Tim Russert of the identity of CIA
agent Valerie Plame, the wife of former ambassador and Bush administration critic Joseph Wilson. Russert has testified before a federal grand jury that he didn’t tell Libby of Plame’s identity.
White House Deputy Chief of Staff Karl Rove told Fitzgerald that he first learned the identity of the CIA agent from syndicated columnist Robert Novak, who was first to report Plame’s name and connection to Wilson. Novak, according to a source familiar with the matter, has given a somewhat different version to the special prosecutor.
These discrepancies may be important because one issue Fitzgerald is investigating is whether Libby, Rove, or other administration officials made false statements during the course of the investigation.
Looks like Libby has a problem.
