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.

The Tar Heel State, where the GOP gubernatorial candidate is steeped in controversy, is a critical battleground in the presidential race.

After a media frenzy over a CNN report claiming Mark Robinson called himself a 'black Nazi,' the Lt. Gov. says he will stay in NC governor race.
