U.S. Sen. Mitch McConnell said he will endorse Kentucky's Republican nominee for governor once the results are official.
Bevin leads state Agriculture Commissioner James Comer by 83 votes out of the more than 214,000 ballots cast. Comer said he plans to ask state election officials to review the results.
McConnell and Bevin went head to head in last year's Republican primary for Senate, one of the few times McConnell has had meaningful opposition in a primary during his 30-year Senate career. McConnell easily defeated Bevin after a contentious campaign. Bevin refused to endorse McConnell publicly after the race, although he did urge Republicans to vote against Democrat Alison Lundergan Grimes in the general election.
McConnell defeated Grimes and is now the majority leader of the U.S. Senate.
