After Novak walked off on Thursday, Henry said that Novak had been told before the segment that he was going to be asked on air about the CIA case.
I don't think so.
Novak is a veteran and would undoubtedly have prepared pat answers regarding any new inquiries on the CIA leak and his role. Given that he had written an article this past week taking on a CIA spokesperson's public comment that he had warned Novak not to print Valerie Wilson's identity, it is something for which he would have prepared.
More likely, he was embarrassed that he had used the word, "BS," demonstrating rank unprofessionalism. He was likely a little shocked himself at the depth of his own reaction and quickly took stock. Having descended into such an emotional rejoinder of Carville, he was unable to recover. And so he left.
I'm frankly surprised we don't see more of this in these ridiculous segments where the usual left/right suspects go at it.
CNN continues to utilize these conservative/liberal segments that are frequently useless for getting any new information or ideas. They rarely advance a discussion. I find them much more interesting when you have independent analysts or journalists, unfortunately a dying breed.
CNN should shake things up, in light of Novak's "time off" and break free from these formulaic time-fillers.
