NEW YORK -- The chairman of Fox News Channel says Donald Trump owes the network's Megyn Kelly an apology for an unprovoked Twitter attack that he called "as unacceptable as it is disturbing."
The Republican presidential front-runner welcomed Kelly back from a vacation Monday night by tweeting that he liked her show better when she was away. He said Kelly "must have had a terrible vacation" because "she's really off her game." He also retweeted a message that referred to Kelly as a bimbo.
Fox News chief Roger Ailes said Tuesday that Kelly "represents the very best of American journalism."
Trump has been attacking Kelly ever since her tough questioning of him during the first GOP presidential debate. It was seen by 24 million people on Fox on Aug. 6.
