Lt. Gov. Mark Robinson, the embattled Republican nominee for governor in North Carolina, was being treated for burn injuries on Friday night after an incident at a campaign event hosted at a truck show in Mount Airy, N.C., according to his spokesman and his political consultant.

Mike Lonergan, Mr. Robinson’s spokesman, said in a text message that the lieutenant governor was “in good spirits.” His consultant, Matt Hurley, echoed that message on Friday night on the social media platform X.

Mr. Robinson was treated for second-degree burns at Northern Regional Hospital in Mount Airy, his campaign said in a statement, adding that he planned to return to campaigning Saturday morning, as scheduled.

At about 5 p.m., Mr. Robinson attended the Mayberry Truck Show in Mount Airy, where dozens of large trucks parade down a street. It was unclear how Mr. Robinson had been injured.

He had spent much of Friday campaigning across the state, including at the headquarters of the Republican Party in Moore County, a Golden Corral restaurant in Laurinburg and a Mexican restaurant in Rockingham.

Mr. Robinson’s campaign has been in turmoil since a CNN report last week linked him to disturbing comments on a porn site. He had told supporters in Moore County on Friday morning that he would remain in the race, defying calls for him to drop out.
