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.

Though it was hard to believe that Mark Robinson could stoop any lower, the Republican nominee for governor of North Carolina found a way.

The Republican candidate running to be governor of North Carolina has denied accusations he called himself a “Black Nazi” on a pornography website and insisted he would not drop out of the race.
