North Carolina Gov. Roy Cooper has withdrawn from consideration to become Vice President Kamala Harris' running mate, the Democrat confirmed on Monday evening.
Sources told the Associated Press that he withdrew from the search in part because of concerns that his Republican lieutenant governor would assume control when he travels out of state if he were selected.
"I strongly support Vice President Harris' campaign for president," he wrote in a statement posted to social media. "I know she's going to win and I was honored to be considered for this role. This just wasn't the right time for North Carolina and for me to be on a national ticket."
"As I've said from the beginning, she has an outstanding list of people from which to choose, and we'll all work to make sure she wins," he added.
Cooper, 67, withdrew before Harris formally began soliciting vetting material from potential vice presidents, the people said. Harris' search is ongoing and her teams of lawyers and political aides are still reviewing information on a narrowing list of potential candidates.
Cooper, the former chairman of the Democratic Governors Association, has been close to Harris since they were both state attorneys general. His potential selection was seen as a possible asset in shifting North Carolina — the Democrats' only significant opportunity to expand on their 2020 map — into Harris' hands.
Under the state constitution, North Carolina Lt. Gov. Mark Robinson, who is the GOP's nominee to replace the term-limited Cooper, becomes acting governor and can assume the Democrat's powers when he travels out of state.
Cooper, according to one of the people, has expressed concern about what Robinson might do if he were to leave the state extensively for campaign travel.
Robinson is an ardent social conservative, who once called abortion "child sacrifice." In various church pulpits, Robinson has asserted men as the rightful leaders in church and society. He once mused that leaders of the original birth control movement in the U.S. were "witches, all of 'em." He has discussed LGBTQ people with words like "filth" and "maggots."
Robinson is running to replace Cooper as the state's governor in November. He is facing North Carolina Attorney General Josh Stein, a Democrat.
The New York Times first reported that Cooper had withdrawn himself from the process, but did not detail the timing of his decision or his rationale. The Harris campaign declined to comment.
Spokespeople for Cooper didn't immediately respond to emails and phone messages late Monday.
