The 2002 National Intelligence Estimate (NIE) was declassified July 18, 2003. link
The article does not refer to specific dates, only that Libby divulged this information "after the Iraq war started" which would be after March 2003.
In addition, I think by definition the President cannot divulge classified information, since he has final authority to declassify something. Even something that is classified by an agency may be appealed to the President for review.
This is covered under EXECUTIVE ORDER 12958
I'm not sure if the Vice President falls under the "supervisory" position under Section 3.1.c.3 of that order.2. Will Libby's "Oliver North" defense be a good strategy for him?
Anyone who has seen "A Few Good Men" knows that that defense is not a valid one, unless the authorizing agent's commission of the same act would not be a crime.3. Assuming this story holds up to scrutiny, what effect will it have on the 2006 and 2008 elections?
Most Americans would probably say "Scooter who?"
