(Reuters) — Alabama Republican Roy Moore filed a court challenge late on Wednesday to the outcome of the U.S. Senate election he lost, hours before officials in the state were due to certify his opponent’s victory.
Doug Jones became the first Democrat in a quarter century to win a Senate seat in the Republican stronghold state when he was declared the winner of the Dec. 12 ballot.
When he takes office, the Republican majority in the upper chamber will narrow to 51 of the 100 seats.
Moore, a former chief justice of the Alabama Supreme Court who stands accused of sexual harassment and pursuing sexual relationships with teenage girls while in his 30s, has not conceded defeat despite being urged by President Donald Trump to do so.
In Wednesday’s filing in the Montgomery Circuit Court, Moore alleged that potential voter fraud had denied him the chance of victory and sought to halt a state canvassing board meeting that is scheduled to ratify Jones’ win on Thursday.
The board consists of Alabama Gov. Kay Ivey, Attorney General Steve Marshall and Secretary of State John Merrill.
“We call on Secretary of State Merrill to delay certification until there is a thorough investigation,” Moore said in a statement posted online by his campaign team.
Moore said three election experts who reviewed the results “agreed that the irregularities in 20 precincts of Jefferson County alone are enough to reverse the outcome of the election.”
Merrill could not be reached for comment after hours.
He told CNN a day after the election that it was “highly unlikely” that Jones, 63 and a former federal prosecutor, would not be certified as the winner.
Jones won the seat, vacated when Jefferson Beauregard Sessions III was tapped by Trump as attorney general, by about 20,000 votes or 1.5 percentage points, election officials said.
In Wednesday’s statement, Moore said his complaint also contained an affidavit from him that he successfully passed a polygraph examination that cleared him of sexual misconduct.
