Donald Trumpâs campaign said Sunday it fired a political aide over racist Facebook posts he allegedly wrote dating back to 2007. Sam Nunberg allegedly wrote racially charged posts including one calling civil-rights leader Al Sharptonâs daughter a racial slur and another describing President Obama as a âSocialist Marxist Islamo Fascist Nazi Appeaser,â Business Insider first reported. Nunberg has denied he wrote the posts, adding that âanything that was posted under my name does not mean I posted it.â Campaign manager Corey Lewandowski said Trumpâs group believes Nunberg wrote the posts and has since fired him.
