Fox acknowledges ‘production error’ and promises ‘disciplinary action’ for misleading Palin footage.

Yesterday, ThinkProgress first reported that Fox News aired old file footage of Sarah Palin rallies to claim that she’s “continuing to draw huge crowds while she’s promoting her brand new book.” Host Gregg Jarrett presented the video with commentary that suggested the footage was “just coming in.” (Watch it.) Media Matters noted that one of the scenes was from a Nov. 1, 2008 Palin rally in Florida. Crooks and Liars’ John Amato filed an FCC complaint for passing on “false information” to the public. By day’s end yesterday, Fox released this statement responding to the controversy:

“This was a production error in which the copy editor changed a script and didn’t alert the control room to update the video,” Michael Clemente, senior vice president of news at FOX, sad this evening. “There will be an on-air explanation during Happening Now on Thursday.”

Citing unnamed sources, The Swamp reports Fox is planning to take “serious disciplinary action” against those “responsible behind the scenes in the control room.”
