Radio host Mark Levin attacked 21st Century Fox CEO Rupert Murdoch and Fox News Channel for “bias” in pro-immigration reform reporting, continuing to grow the divide between conservative talk radio hosts and the network.

On the July 15 edition of his radio show, Levin -- who has previously called the immigration reform bill a "disgusting disgrace" and a "crap sandwich" -- discussed a recent tweet by Murdoch, chairman and CEO of Fox News' parent company 21st Century Fox, that declared Sen. Harry Reid (D-NV) was correct about the immigration reform effort and expressed support for the immigration reform bill. Levin then accused Fox News of biased reporting on immigration reform and accused “a number of hosts” who support immigration reform of not reading the bill:

This isn't the first time Levin has taken issue with what he referred to as “our favorite cable channel.” On the July 12 edition of his show, Levin attacked Fox News contributor Karl Rove over his support for immigration reform saying, “you know what number Karl Rove never puts on that whiteboard? His win-loss percentage.”

Earlier this month, both Levin and fellow conservative radio host Rush Limbaugh appeared on Fox, but neither was asked about immigration reform, despite their well-known outspokenness on the immigration reform effort. After Limbaugh's interview, he went on his radio show to criticize the network and claim that Fox wouldn't allow him to discuss the immigration reform effort. Yet, after walking back his comments, Limbaugh was allowed to speak on the topic during Fox News' The Five for almost ten minutes.

In addition to a conservative radio schism, conservatives in print media have also pitted themselves against one another over immigration, most recently between New York Times columnist David Brooks -- an immigration reform supporter -- and National Review's Rich Lowry and The Weekly Standard's Bill Kristol, who wrote an op-ed calling on House Republicans to "[put] a stake through" comprehensive immigration reform.
