The Obama administration has called Fox News "a wing of the Republican Party" but even the White House might be surprised to find out that more than 30 network personalities have supported GOP candidates this year.

A new report by the liberal group Media Matters claims that in more than 600 instances Fox News personalities have "endorsed, raised money, or campaigned for Republican candidates or organizations."

Some of the personalities are Fox News contributors that have been Republican candidates or worked for Republican administrations in the past. It's probably no surprise that Monica Crowley, Newt Gingrich, Mike Huckabee, Sarah Palin, Dana Perino, Karl Rove and Rick Santorum have endorsed or otherwise supported Republican candidates.

Huckabee alone has endorsed 113 candidates. Palin has endorsed 93 and Gingrich has endorsed 41.

Other personalities highlighted are Fox News hosts that have well known conservative views. Glenn Beck has spoken in favor of Kentucky Republican Senate candidate Rand Paul, Connecticut Republican Senate candidate Linda McMahon, and Minnesota Republican congressional candidate Michele Bachmann.

Media Matters notes that Sean Hannity has lent his support for eight candidates as well as a March fundraiser for the National Republican Congressional Committee and a book signing at the Southern Republican Leadership Conference.

Eric Bolling, Laura Ingraham, Brian Kilmeade, Andrew Napolitano and Stuart Varney were other personalities mentioned that regularly host or guest host shows on Fox News or Fox Business Network.

The report will most likely add fuel to the argument that Fox News is a biased organization. In October 2009, the White House briefly stopped doing interviews with the channel.

"Fox News often operates almost as either the research arm or the communications arm of the Republican Party," said White House communications director Anita Dunn.

Later that month, a Pew poll found that Americans believed the network to be the most ideological channel with 47 percent saying it was "mostly conservative."

In January, Public Policy Polling survey found that Fox News was the most trusted of all news networks. 49 percent said they trust Fox News while 37 percent said they did not.
