Oh, the fact that Mrs. Wilson worked at the CIA has been established to be classified information?!

I'm sure you know this as well, but I don't think the CIA makes a habit of confirming classified info just because it has been leaked. But anyone who believes she wasn't covert should be outraged that an investigation even exists, since establishing that basic fact would end the entire matter immediately and it wouldn't matter in the least who said what to whom.
