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.

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.

A North Carolina loss could not only foil Trump’s re-election chances, it would be a particular home-state humiliation for his two handpicked co-chairs of the Republican National Committee: Michael Whatley, who is the state’s former GOP chair, and Lara Trump, the former president’s daughter-in-law, who is a North Carolina native.
