Brit Hume's true colors show on Sundays, when he appears on Fox News Sundays. Previously, Hume had declared that it was "unlikely" that Valerie Plame Wilson carried out covert missions for the CIA. (How he could presume to know such a thing is beyond me.) The evidence is mounting that Plame was in fact a covert operative, including statements by the CIA director and Ms. Plame herself, in her sworn congressional testimony on Friday. But Brit knows best: He's accusing Plame of lying under oath.
