You're missing my point big time. For Fitzgerald not to be sure of Plame's CIA classified status at the time in question, at this point in the investigation, is to me, absurd.
He does know. It's implausible that he doesn't.
But he can't reveal whether Plame has or did have covert status, because that would be a violation of the Intelligence Identities Protection Act.
Saying that Plame's position was "classified" is not a violation of the Intelligence Identities Protection Act.
"Covert" and "classified" are two very different things under the law.
