Donald Trump’s campaign declined to comment Thursday on whether North Carolina Lt. Gov. Mark Robinson, whom the former president once described as “Martin Luther King on steroids,” should drop out of the battleground state’s race for governor.

North Carolina Lt.t Gov. Mark Robinson, the Republican nominee for governor in that state, denied the accusations put forth in a CNN story published Thursday that he left numerous graphic comments on a porn site’s message board.

Robinson denied the CNN report, which said he referred to himself as a "black NAZI" and expressed support for bringing back slavery more than 10 years ago.
