"No one cares whether or not she was covert."
It seems to me that Fitzgerald is drawing a distinction between "covert" and "classified". He's saying that Plame's status was classified. If Plame was covert within the meaning of the statute, a whole bunch of people would have been indicted a long time ago.
That's exactly right and thanks for reminding me of that.
Fitz said that Plame's status was classified. Not covert.
