"With the inauguration of President Obama in 2009, Fox News transformed itself from a conservative media outlet into a partisan, right-wing political organization that openly viewed itself as the "voice of the opposition." Throughout the year, Fox News has declared war on the Obama administration, the Democratic Congress, and progressive organizations by, among other things, campaigning for the firing of various administration officials, partnering with conservative groups and politicians to oppose progressive policies, and even allowing its own contributors to fundraise on-air for conservative political causes."
