Republican Roy Moore remains defiant over the December 12 election results for the Alabama Senate seat vacated by Attorney General Jeff Sessions. Moore has yet to formally concede and has filed a lawsuit to delay the certification of his opponent, Democrat Doug Jones, who won the election by about 20,000 votes.

In the suit, Moore, whose campaign was derailed by allegations of sexual misconduct, said he took a lie detector test following the election that he says proves his innocence.

"Also provided in the complaint is an affidavit from Judge Roy Moore stating that he successfully completed a polygraph test confirming the representations of misconduct made against him during the campaign are completely false," said Moore's campaign in a statement released Wednesday.

During the election for the Senate seat, multiple women came forward to accuse Moore of having inappropriate relations with them when they were teenagers and he was in his 30s. “One woman says she was 14 years old when Moore touched her sexually. Another accuser said Moore assaulted her when she was 16 years old, pushing her head towards his crotch in a locked car,” notes The Hill.

Moore filed the lawsuit hours before Alabama Secretary of State John Merrill is set to certify Jones as the election winner. The suit claims election "irregularities" and calls for an investigation into voter fraud. "In the complaint, Moore’s attorneys noted the higher than expected turnout in the race, particularly in Jefferson County, and said that Moore's numbers were suspiciously low in about 20 Jefferson County precincts," reports the Associated Press.

"The purpose of the complaint is to preserve evidence of potential election fraud and to postpone the certification of Alabama’s Special Election by Secretary of State John Merrill until a thorough investigation of potential election fraud, that improperly altered the outcome of this election, is conducted," reads a statement from the Moore campaign.

Jones' spokesman Sam Coleman said the suit's "desperate attempt by Roy Moore to subvert the will of the people will not succeed."

"The election is over, it's time to move on," Coleman told The Hill.

Earlier this month, Merrill confirmed that an investigation into voter fraud was opened after a video went viral of a Jones supporter seemingly bragging about traveling from out of state to vote for the Democrat.
