The senior Senate Republican Lindsey Graham has said reports that the North Carolina Republican candidate for governor, Mark Robinson, calling himself a “black NAZI!” in posts on the porn forum Nude Africa a decade ago are “beyond unnerving” and should see him end his political career if proven true.

“If they’re true, he’s unfit to serve for office,” the long-serving South Carolina senator said Sunday. “If they’re not true, he has the best lawsuit in the history of the country for libel.”
