It's old news by now (read Josh Marshall's summary if you're not up on it). I only bring it up because the whole Valerie Plame Wilson scandal has become such a farce and continues to get more ridiculous every day. It's unfortunate that the special prosecutor was put into a situation in which the focus of the investigation seems to be to justify its own existence.
Congress is the place where alleged political misconduct should be investigated. As it is now, both the admin and the prosecutor's office are leaking like sieves about a supposed leak investigation. Instead of fighting a proxy battle through the press, the admin and its opponents should be doing it the old-fashioned way, in a Capitol Hill hearing room.
