"Fox News has been criticized for unethical behavior in the past and for operating like a political organization. In fact, Crowley crossed the ethical line during the 2012 presidential election when she spoke at an anti-Obama rally sponsored by the Koch-funded conservative advocacy group, Americans for Prosperity.
Fox News has long styled itself as an anti-immigrant network even as it purports to reach out to Latino viewers. Rush Limbaugh, for example, stated in January that it's "up to me and Fox News" to defeat immigration reform. As Yahoo! News noted however, Limbaugh was "notably absent" from the list of signatories."
