TalkLeft: Fitzgerald, Cooper, Sauber, Rove , Luskin and Ginsberg:

"Sauber says that Fitzgerald isn't disclosing his hand, either in conversation or in body language.
LT: From all that you've heard and all of the people you have spoken to, what do you think Fitzgerald is aiming for?
RS: I spent a lot of time on the phone [with Fitzgerald] and in person. He was so careful not to give away anything -- even with body language -- any indication of what he was looking at or where he was going. It was quite astonishing how uncommunicative he was. So the short answer is, I don't know.
But the only clue is that he submitted some fairly extensive material under seal. Every judge who has commented on that [has said] how impressive the showing is and how important this case is to national security. All I can surmise is that he has a substantial amount of evidence to continue a fairly robust investigation. And it does involve classified material."
