Robert Novak walked off the set during the “Strategy Session” on the second-to-last day of Inside Politics. It happened at 4:50pm, during a debate with James Carville. The two argued, and Carville said: “He’s gotta show these right-wingers that he’s got backbone. The Wall Street Journal editorial board is watching, show ’em you’re tough.” Novak responded: “Well I think that’s bullshit, and I hate that. Just let it go.” Two seconds later, he stood up and walked off.
Media Matters has the video.
UPDATE: CNN has asked Novak to take some time off.
