If Patrick Fitzgerald knows who first leaked Valerie Plame's name to Robert Novak, he still isn't saying. The indictment filed against Scooter Libby today refers to the "senior administration official" as "Mr. A" -- and says that Libby was aware that "Mr. A" had leaked to Novak.
Correction: The reference to the "senior administration official" who leaked Plame's identity to Novak comes from the press release issued by Fitzgerald's office, not from the indictment, and Fitzgerald identifies the official as "Official A," not "Mr. A."
