what a d-bag...

NEW YORK -- CNN suspended commentator Robert Novak indefinitely after he swore and walked off the set Thursday during a debate with Democratic operative James Carville.

The live exchange during CNN's "Inside Politics" came during a discussion of Florida's Senate campaign. CNN correspondent Ed Henry noted when it was over that he had been about to ask Novak about his role in the investigation of the leak of a CIA officer's identity.

A CNN spokeswoman, Edie Emery, called Novak's behavior "inexcusable and unacceptable." Novak apologized to CNN, and CNN was apologizing to viewers, she said.

"We've asked Mr. Novak to take some time off," she said.

A telephone message at Novak's office was not immediately returned Thursday.
