I wouldn't trust anything Fitzgerald says. He's probably already got the Cheney indictment 90 percent complete, only needing the guilty verdict and the leverage it provides over Libby to fill in the few remaining blanks. His lie about not pursuing further charges is probably intended to keep the shredders in offices all over DC from kicking into hyperdrive (not that this would really happen, but this is how Dims think).
"He's probably already got the Cheney indictment 90 percent complete"
You could very well be right on that.
