Robert Novak's principles

Remember how Robert Novak refuses to reveal who outed CIA operative Valerie Plame? Well, his journalistic principles seem rather fluid (from Atrios).

Fellow panelist, Al Hunt, from the Wall Street Journal, then replied: "Robert Novak, you're saying CBS should reveal its source?"

The transcript continues:

NOVAK: Yes.

HUNT: You do? You think reporters ought to reveal sources?

NOVAK: No, no. Wait a minute.

It's rather funny how lame Novak is.
