As Media Matters' Dianna Parker noted just minutes ago, News Corp chief Rupert Murdoch appeared on Fox & Friends this morning with New York City Mayor Michael Bloomberg to discuss their support for comprehensive immigration reform. For his part, Fox & Friends co-host (and Murdoch employee) Steve Doocy seemed to be on his best behavior:

Steve Doocy hosted Murdoch and NYC Mayor Michael Bloomberg on Fox & Friends to talk about their about immigration reform efforts, and the tone of the discussion was pretty measured and -- dare I say -- pro-immigrant.

It was not the tone Fox News usually employs when talking about immigration. There was no typical scare-tactic b-roll of people appearing to cross the U.S.-Mexico border illegally by crawling over fences, no crowing about “amnesty,” no outrage over immigrants stealing American jobs or getting fair wages, and no baseless suggestions that all immigrants are criminals. Get this: Doocy even used the phrase “undocumented immigrants,” instead of slinging around the charged word “illegals,” like he and his co-hosts do in virtually every other segment on immigration. It was like watching a completely different network.

But how far reaching will this promising change in attitude on such an important issue extend?

If the right-wing cable outlet's horrific coverage of global climate change despite Murdoch's efforts to fight the problem is to be any indication, not far at all. As Media Matters' has repeatedly noted:

News Corp. CEO Rupert Murdoch has stated that News Corp. “can set an example” and “reach our audiences” when it comes to fighting climate change, promising in 2007 to make all of News Corp.'s operations carbon neutral by 2010 and most recently commissioning pollster Frank Luntz to conduct a survey that reportedly studied the most effective way to communicate with voters on climate change. However, media figures at his news outlets, including Fox News and the Wall Street Journal, have routinely advanced false and misleading claims in denying climate change.

Remember, this is the same cable network that recently announced plans to launch a new website (FoxNewsLatino.com) targeting the Latino community despite its long history of pushing misinformation surrounding all things even remotely tied to immigration.
