Commenter Mike Sylwester explains sundance's theory pretty well. Here's Mike's statement of the facts as I understand sundance to be presenting them. I'll add a bit more:
It seems that Senator Mark Warner told James Wolfe to leak the Page FISA warrant to the New York Times. Wolfe (and Warner) were caught by the FBI, but then DOJ/FBI covered up the crime. Wolfe was not charged for leaking the top-secret FISA warrant. Rather, he was charged only for lying to the FBI.
Exactly who made the decision to reduce the charge against Wolfe from leaking to merely lying? Who approved that decision? What was the justification?
There are three additional contentions that sundance is making in connection with the Wolfe case, and they all suffer from the same problem.
First, sundance also maintains that DoJ/FBI have an official position that the Page FISA wasn't leaked by Wolfe. To support that he cites the Wolfe sentencing memo:
The very obvious problem with this--as Shipwreckedcrew is quick to point out--is that the FBI (and DoJ) are NOT saying they don't believe Wolfe did the leak. They're only saying, in effect, that they don't have the evidence to prove that beyond a reasonable doubt. I happen to believe that sundance is right, that Wolfe did the leak. The circumstantial evidence is very strong. And although I'm not a betting person, I would happily bet that every single FBI agent who worked that case also believes Wolfe did it. The problem is the lack of physical evidence--destroyed by Wolfe. Here's SWC's explanation:
