Real-estate magnate Donald Trump's presidential campaign is filled with internal conflict, New York magazine reported Thursday. "It turns out that, inside a campaign that's been built on attacking seemingly anyone and everyone, the staff has now turned to attacking each other," Gabriel Sherman wrote. Sherman added that the campaign's "civil war" broke out into the public view after Business Insider revealed a Trump adviser's history of racially provocative Facebook posts last week. The adviser, Sam Nunberg, was fired from the campaign as a result on Sunday.
