"In late August 2006, former U.S. Deputy Secretary of State Richard Armitage revealed publicly that Novak had based his disclosure of Mrs. Wilson's CIA identity on then still-classified information that Armitage initially gave him while Armitage was still serving in the State Department." http://en.wikipedia.org/wiki/Plame_affair_timeline
"In any case, it was clearly not a good idea for Richard Armitage to reveal her identity to Bob Novak."
Let's keep the established facts straight.
Otherwise, since you're ignoring my statement that she was no longer a covert agent when this happened, I'm not sure what's the point of your reply.
Richard Armitage is also accused of leaking Plame's identity, and first, but that didn't make it less of a crime for Libby to do so as well.
