Donald Trump called allegedly self-professed “Black Nazi” Mark Robinson “better than MLK” when he endorsed him to be the next North Carolina governor. Trump appeared at Robinson’s rally in March and adoringly talked up the lieutenant governor as he stood beside him on stage.

Trump has yet to speak out as Robinson faces pressures to exit the North Carolina gubernatorial race after reports of his past messages to an adult website.

Mark Robinson, the Republican nominee for governor in North Carolina was exposed Thursday afternoon for an extensive comment history on a pornography forum called “Nude Africa” where he called himself a “Black Nazi,” attacked Martin Luther King Jr. repeatedly, and even talked about buying slaves if it became legal again.
