It was Robert Novak. He was interviewing Plames husband who is protected by the spouse exception and whether intentional or not let it slip. Whether Libby also let it slip was never established but he was the fall guy after he made a mental slip in testimony. You dont have to lie under oath to be found guilty of perjury anymore you just need to make a mental slip. Libby was conflicted with what he knew he could say and what he knew and so he was crucified for a mis-statement. Novak somehow got a pass and I still dont understand that but it was he that wrote about Plames identity.
Plame was a 'disposible asset' anyway and she never had the natural resources to be more then a message courier but as a covert opperative her identity should have been kept secret. She is well suited for the search for 'victim compensation' that has become popular in our courts.
Somehow this part of Wilsons interview received more attention then the fact that he claimed to routinely take SR71 flights.
