Divided: Levin 'Exposes' Krauthammer

"I stand exposed as the longest, secret mole of liberals and democrats in the conservative movement in the history of the Republic."

Washington Post columnist Charles Krauthammer reacted to criticism from conservative radio host Mark Levin, who had taken to his radio show on Tuesday night to remind his listeners that Krauthammer once worked a speechwriter for the 1984 Democratic presidential nominee, former Vice President Walter Mondale.
