This refers to Obama's various attempts to marginalize Fox News. One attempt to exclude Fox from the normal five channel rotation failed when ABC/CBS/NBC/CNN refused to participate without Fox:
Some people credit ABC/CBS/NBC/CNN with high-minded freedom-of-the-press motives. I don't. I suspect someone just explained to them what accepting this precedent would mean the next time that a Republican was president.
What is Obama's real problem with Fox? Likely, it is that Fox reports stories the other media ignore, such as the ACORN and Van Jones videos. Rich Lowery comments (hat tip Instapundit):
This New York Times account today confirms that what most bothered the White House about Fox is that it caused inconvenient reporting by other news organizations. Can't have that! .... In other words, their problem is not that Fox isn't a real news organization, their problem is that it is.
