I concur with Outraged. The host of Inside Politics and Carville were having a "lovefest", not allowing Novak to answer the questions without interruption and Novak walked out with a look of disgust.
The host tried to cover it up after the commercial saying it was sort of "planned" because he had told Bob he was going to ask him about the CIA leak. If that was the case, Bob would have left during the commercial break.
CNN has a bit of egg on it's face.
That would then make the host a proven liar (shocking I know), as it was more than obvious that Novak's walk was spontaneous/unexpected...the tension was palpable and the nervousness apparent as the host and Snakehead were having intercourse (pun intended).
