CNN’s “Reliable Sources” is hosted by Howard Kurtz, who also pulls double-duty as the media reporter for The Washington Post. Kurtz recently took on Patrick Gavin, a reporter for Politico, during a segment of his show. He said he was just “poking fun” at Gavin, but the blogosphere did not take it lightly. TVNewser sister blog Fishbowl DC explains the controversy, and has a couple of questions for Kurtz about the segment.
