North Carolina Republican Mark Harris said Friday he’s open to a new election in the 9th District, where allegations of election fraud have thrown his victory into question.

The state board of elections is investigating absentee voting irregularities and confirmed Friday that a contractor for the Harris campaign is a person of interest in connection with an alleged absentee ballot operation. 

“Although I was absolutely unaware of any wrongdoing, that will not prevent me from cooperating in this investigation,” Harris said in a video message posted on his Twitter account Thursday afternoon. 

“However, if this investigation finds proof of illegal activity on either side — to such a level that it could have changed the outcome of the election — then I would wholeheartedly support a new election to ensure all voters have confidence in the results,” Harris said.

The Associated Press called the race for Harris three days after Election Day when Harris led Democrat Dan McCready by about 900 votes. But with the state delaying certification of the results and investigating allegations of fraud, the AP has retracted its call. McCready retracted his concession on Thursday.
