NO, NO, NO. He is charged with lying to the FBI and the federal grand jury about how and when he found out that Wilson's wife worked for the CIA. He said he heard that from Russert so he couldnt have been telling that to reporters. They were telling him that. Unfortunately several people in the CIA, several people at state told him much earlier and Libby used that information reporting it to Cheney and discussing what to do about it in various staff meetings. Then he tried to get Fleischer to leak to press. When questionned about it, he concocted a story that is laughable on its face. He had known for months what he said Russert has just told him. He lied. Whether or not Plame was covert is totally irrelevant.
Now, I know you are pulling this out of the ether.
It is uncontested that he told investigators from day one he heard this detail from Cheney on June 12.
He says he forgot about it in the press of business(because as every witness said it was not signficant then)but he had a "eureka" moment if you will when reporters started askng him about it.
Among the reporters who obviously knew were Woodward, Novak, Cooper, Mitchell"everyone knew", and now, if one believes Fleischer, Gregory and Dickerson.
Also who knew but were not questioned Kristof and Corn and Judis, etc.
And some like Russert were barely questioned.
