Who do you think it is?
Russert on 3 of the 5 counts. Russert had a secret conversation with a now retired FBI agent whose notes are lost. Russert then withheld this conversation from the subpoena. There's solid reason to question whether his testimony should be impeached.
Clearly you are convinced that he's guilty. I am not persuaded.
Not because he's conservative-- if I were persuaded that he did it, I would want him punished for his crime for the reason that I don't believe in a double standard when it comes to the rule of law. And the rule of law mandates that if Russert and Mitchell were making accusations about Libby to the FBI, then Libby has a right to confront them in trial.
Moreover, there is so much evidence that there was greater incentive for the reporters to lie than for Libby. It's reasonable to question it. It doesn't mean necessarily that they did lie, but it warrants closer and more vigorous scrutiny.
BTW Libby's friends assisting him include liberal editor of the New Republic, Marty Peretz.
You and I disagree. We just different sources and have different understandings of the case.
