Via New York Times:
Few things seem to pique President Obama like Fox News. ...
The White House insists that the president does not have a preoccupation with Fox News, and that both of the president’s recent Fox quips were ad-libbed. The remark in Ohio came in an unrehearsed exchange with a potential voter. And the “Uncle Jim” comment, while uttered during a campaign speech, was not part of the written text.
Isn't it more evidence that President Obama is a little preoccupied with Fox News if it's something that he mentions when not reading from prepared remarks?
