MONTGOMERY, AL — Roy Moore filed an election complaint on Wednesday, alleging potential voter fraud in Alabama’s special election and urged a delay in certifying the results.

Moore, a Republican, has refused to concede after losing the Senate race on Dec. 12 to Democrat Doug Jones by more than 20,000 votes.

Alabama Secretary of State John Merrill is slated to certify the special election results Thursday. But the Moore campaign launched a last-minute court battle to stop state officials from certifying Jones as the winner, saying it should be delayed until a “thorough investigation of potential election fraud,” according to his press release.

CNN reached out to the Alabama Secretary of State’s office for comment on whether Moore’s filing would affect the process. Previously, Merrill has said it is “highly unlikely” that Jones would not be certified as the winner of the election.

Moore and his campaign filed a complaint in the Circuit Court of Montgomery, Alabama, listing several allegations and called for “a new special election.”

His complaint alleges that out-of-state residents had been allowed to vote and that election fraud experts had concluded through statistical analyses that fraud had taken place. One of the election experts Moore cites is Richard Charnin, who also posts about JFK conspiracy theories and the murder of DNC staffer, Seth Rich.

Moore’s complaint also alleged “anomalous” higher voter turnout in Jefferson County, in which census data shows 43% of the population is black. He called the county’s 47% voter turnout as “highly unusual” and questioned the integrity of its election results.

Jones is the first Democrat in a generation to win a Senate seat in Alabama, beating Moore amid a firestorm of allegations that the GOP candidate had sexually abused teens.

In his election complaint, Moore stated that he took a polygraph test over the sexual misconduct allegations made against him by Leigh Corfman, Beverly Nelson and Tina Johnson. Moore says that he took the polygraph test after the December 12 election, according to his affidavit, included in the complaint.

In the affidavit Moore states, “the results of the examination reflected that I did not know, nor had I ever had any sexual contact with any of these individuals.”

He called the allegations “false and malicious attacks on my character.”

In a press release, Moore implored supporters to call state officials to delay certifying the results.
