CNN: Libby has resigned.
He should have resigned earlier IMHO -- he knew what he did and to stay makes his boss look bad. There is more to this story then is coming out but somehow I don't think Libby made a good decision at all.
Maybe this will be a lesson to those in the WH -- don't talk to RAT reporters that are married to Clintonties. They have been playing nice with the reporters and RATs for way too long and it bit them.
