ATLANTA — The FBI on Wednesday searched the election office of a Georgia county that has been central to right-wing conspiracy theories over President Donald Trump’s 2020 election loss, acting just one week after the Republican leader predicted prosecutions over a contest he has baselessly insisted was tainted by widespread fraud.

The search at Fulton County’s main election facility in Union City sought records related to the 2020 election, county spokesperson Jessica Corbitt-Dominguez said. It appeared to be the most public step by law enforcement to pursue Trump’s claims of a stolen election, grievances rejected time and again by courts and state and federal officials, who found no evidence of fraud that would have altered the outcome.

It also unfolds against the backdrop of FBI and Justice Department efforts to investigate perceived political enemies of Trump, including former FBI Director James Comey and New York Attorney General Letitia James.

Trump has for years focused on Fulton, Georgia’s most populous county and a Democratic stronghold, as a key example of what he claims went wrong in the 2020 election. His pressure campaign there culminated in a sweeping state indictment accusing him and 18 others of illegally trying to overturn the vote.

An FBI spokesperson said agents were “executing a court authorized law enforcement action” at the county’s main election office in Union City, just south of Atlanta. The spokesperson declined to provide any further information, citing an ongoing matter.

Corbitt-Dominguez said a warrant “sought a number of records related to 2020 elections,” but declined to comment further because the search was still underway.

The Justice Department had no immediate comment.

Trump has long insisted that the 2020 election was stolen even though judges across the country and his own attorney general said they found no evidence of widespread fault that tipped the contest in Democrat Joe Biden’s favor.

The president has made Georgia, one of the battleground states he lost in 2020, a central target for his complaints about the election and memorably pushed its secretary of state to help “find” enough votes to overturn the contest.

Last week, in reference to the 2020 election, he asserted that “people will soon be prosecuted for what they did.” It was not clear what in particular he was referring to.

Fulton County District Attorney Fani Willis in August 2023 obtained an indictment against Trump and 18 others, accusing them of participating in a wide-ranging scheme to illegally try to overturn the results of the 2020 presidential election. That case was dismissed in November after courts barred Willis and her office from pursuing it because of an “appearance of impropriety” stemming from a romantic relationship she had with a prosecutor she had hired to lead the case.

The FBI last week moved to replace its top agent in Atlanta, Paul W. Brown, according to people familiar with the matter who spoke on condition of anonymity to discuss a non-public personnel decision. It was not immediately clear why the move, which was not publicized by the FBI, was made.

The Department of Justice last month sued the clerk of the Fulton County superior and magistrate courts in federal court seeking access to documents from the 2020 election in the county. The lawsuit said the department sent a letter to the clerk, Che Alexander, but that she had failed to produce the requested documents.

Alexander has filed a motion to dismiss the suit. The Justice Department complaint says that the purpose of its request was “ascertaining Georgia’s compliance with various federal election laws.”
