Howard Kurtz Leaving CNN for Fox

Has had some recent credibility problems

In a big shakeup in the world of media and television, reporter and critic Howard Kurtz is leaving CNN and joining Fox News, the network announced on Thursday.

Kurtz, who hosted CNN's Reliable Sources, will anchor a weekend media program for Fox News and write a weekly column for FoxNews.com, Fox News executive vice president of news Michael Clemente said in a press release. Kurtz starts his new gig at Fox News on July 1.

The surprise move marks the start of the next phase in the career of one of Washington's long-running and best-known media reporters, a journalist who was once well regarded but whose star has dimmed as the errors have piled up. Kurtz's run has been plagued at times by a handful of whopping mistakes, including most recently inaccurately claiming that an NBA player who came out as gay had failed to reveal he had once been engaged.

While Kurtz has dinged Fox News from time to time for its coverage, including recently on the attack in Benghazi, Libya, he was never part of the pack of Fox haters, and he has maintained an open line of communication with network boss Roger Ailes over the years.
