(CNN) - Organizing for America, President Obama's political organization that is now run out of the Democratic National Committee, sent a fundraising email to supporters Thursday that highlights a $1 million donation from News Corp. to the Republican Governors Association.
News Corp. is the parent company of Fox News, an organization the White House has sparred with in the past. In October, White House Communications Director Anita Dunn said, "The reality of it is that Fox often operates almost as either the research arm or the communications arm of the Republican Party."
That sentiment was echoed in Thursday's fundraising email.
"News Corp. - the parent company of Fox News - just donated $1 million to the Republican Governors Association, an official organization campaigning against Democrats all over the country this fall," Organizing for America director Mitch Stewart said in the e-mail. "It's one thing to echo Republican talking points and hire Sarah Palin for political 'analysis.' It's another thing to cut those Republicans a seven-figure check to fund their attack ads and robo-calls."
A CNN review of financial contributions made by media corporations showed that the parent companies of CNN, ABC, CBS and NBC have all made at least six-figure contributions to political parties and candidates. But none of them has given one political organization such a large sum, without a significant contribution to the opposing party.
On Wednesday, the executive director of the Democratic Governors Association, Nathan Daschle, called on the cable news network to run a "formal disclaimer" when it covers gubernatorial races.
Fox News' response indicates a disclaimer will not likely be forthcoming.
"Nathan's stunt has run its course," Fox News spokesman Brian Lewis said in a statement to Washington Post media columnist and CNN contributor Howard Kurtz. "His 15 minutes are up. Time to leave the stage."
