I'm sure that site added that information after the Plame story hit the fan.
You'll get no argument from me that Mrs. Wilson was not a covert agent, nor had she been one recently enough to fit the "Agee" law.
And if she couldn't wait to tell Wilson she was a spy (which she did in a foreign country on their THIRD date), then I'm sure she's told plenty of people. But probably not Karl Rove or Scooter Libby.
If I had a farm I would bet that either she or Wilson or someone who worked with them or knew them had told this to Miller, and Miller passed this on to Libby on July 6, 2003.
And that's why Miller won't talk.
And the simple, clear fact that there could not possibly have been a crime somehow escaped the notice of the CIA before it requested an inquiry, and hasn't come to Patrick Fitzgerald's attention in the last two years.
Sorry. No way it's going to be that easy.
