Republican Mark Harris said Tuesday he will not run in the new election for North Carolina’s 9th congressional district, citing his “extremely serious” health condition.

It comes just days after the North Carolina State Board of Election unanimously voted for a new election after the district’s House race from 2018 was marred by claims of ballot fraud.

NORTH CAROLINA ELECTION BOARD CALLS NEW ELECTION IN DISPUTED HOUSE RACE

“After consulting with my physicians, there are several things that my health situation requires as a result of the extremely serious condition that I faced in mid-January,” Harris said in a statement. “One of those is a necessary surgery that is now scheduled for the last week in March.”

Harris added, “I have decided not to file in the new election for Congressional District 9.”

Last week, Harris, who outpaced Democrat Dan McCready by 905 votes in the contested race, said in court he has suffered two strokes since the election and was “struggling” to get through the hearing.

McCready has said he will run again.

In his statement Tuesday, Harris threw his support behind Union County Commissioner Stony Rushing.

"The North Carolina Republican Party fully supports Dr. Harris' decision,” North Carolina Republican Chairman Robin Hayes said. “The most important thing for him to address is his health. This has been a grueling process for all involved, and we unequivocally support his call for a new election.”

Last week, Harris acknowledged a new election should be held after days of testimony in a hearing on ballot-tampering.

“I believe a new election should be called,” Harris said. “It’s become clear to me that public confidence in the 9th District has been undermined to an extent that a new election is warranted.”

In his sworn testimony, Harris said that he was assured by political operative – and convicted felon – Leslie McCrae Dowless that campaign workers would never collect absentee ballots, despite concerns from Harris’ son, John, that Dowless was illegally collecting and turning in ballots from voters.

One of the methods participants said Dowless used was to hire workers to collect absentee ballots from voters who received them, and then turn them over to him, according to an elections board investigation.

State election law prohibits anyone other than a guardian or close family member from handling mail-in ballots. Harris' team initially said in a legal briefing submitted to the elections board last week the board should certify him the winner -- no matter what Dowless did for the campaign.

Harris’ comments calling for a new election came a day after his son took the stand in emotional testimony that left his father in tears.

"I raised red flags at the time the decision was made to hire Mr. Dowless," John Harris said in his testimony on Wednesday.
