In other media news, Robert Novak has left CNN and joined Fox News. Novak was a regular on Crossfire up until the political show’s cancelationearlier this year. Novak hadn’t been on air since he walked off a live set in August during a debate. In July 2003 Novak outted Valerie Plame in a newspaper column as an undercover CIA operative leading to a scandal that has so far forced one top administration official–Lewis Scooter Libby–to resign. Novak has never publicly revealed his source of the leak but last week said he was “confident the president knows who the source is.”
