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 is critical to Trump’s most plausible paths to victory, and polls showed him neck-and-neck with Harris there even before new scandal enveloped the GOP gubernatorial nominee.

North Carolina Lt. Gov. Mark Robinson will not appear at former President Donald Trump’s rally in the eastern part of his state after a CNN report about his alleged posts on a pornography website’s message board.
