The Republican candidate in an unresolved North Carolina congressional race says he would back a new election if a probe proves that fraud swayed the race’s outcome.

Mark Harris released a video statement Friday addressing an investigation into absentee ballot fraud allegations in the district where he holds a slim lead in unofficial results. The state elections board has refused to certify results while it conducts an investigation.

Harris said in the statement that if it’s proven that illegal activity changed the outcome of the race, he would “wholeheartedly support a new election.”

Harris also repeated that he knew of no wrongdoing during the campaign but that he’s fully cooperating with the state investigation.
