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.

He called himself a “Black Nazi,” supported reviving slavery, and bashed Martin Luther King Jr., all on an old porn website where he used to write.

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.
