Sure looks like Karl Rove… and someone else… betrayed CIA agent Valerie Plame, acting as retribution for her husband blowing the whistle on a White House lie. There might be a possible "knowing disclosure" defense, which should fool no one.
There's some speculation we might see Rove led off in handcuffs, but I don't think this will happen. Rove, along with Bob Novak (who appears to be a White House spokesman), is what they call a "made man" in that subculture, and will probably be above the law. Novak's apparently made a similar arrangement.
