The FBI said in a brief statement its agents executed a warrant at the Fulton County Election Hub and Operation Centre in Union City, a large, warehouse-like facility opened by Georgia officials in 2023, and called it a "court-authorised law enforcement activity".
The warrant "sought a number of records related to 2020 elections", the Fulton County government said in a brief statement.
The FBI agents were looking to seize computers and ballots they believed were held at the facility as part of an investigation into possible election interference, a law enforcement official told Reuters, speaking on condition of anonymity.
The search was conducted a week after Trump reiterated during comments in Davos, Switzerland, his longstanding and debunked claim the 2020 voting "was a rigged election".
"People will soon be prosecuted for what they did," Trump said in Davos.
FBI director Kash Patel was appointed to his post by Trump in 2025.
Joe Biden, a Democrat, won Georgia and defeated Trump, a Republican who was seeking re-election in 2020. Trump returned to the presidency for a second term in 2025 after winning the 2024 election.
The Trump administration separately began a lawsuit in December to get hold of Fulton County's 2020 ballots.
In the suit, the administration said the ballots and other records being sought were in the custody of the Fulton County Superior Court in Atlanta. It was not clear where the ballots were being stored.
The administration has asked a federal judge to order Che Alexander, Fulton County's court clerk, to hand over "physical ballots, stubs and absentee ballot envelopes for the 2020 General Election".
Alexander in January asked the court to dismiss the lawsuit, noting the ballots she holds are under seal under state law, and the administration should instead ask the county Superior Court for an order to unseal them. Alexander did not immediately respond to a request for comment.
The Democratic-leaning county is home to Atlanta, Georgia's biggest city, and backed Biden by a wide margin in the 2020 election.
Trump unsuccessfully sought to overturn the 2020 election result, pressuring Georgia's top election official to "find" votes that would allow him to claim victory.
Several reviews and a hand audit of ballots confirmed Biden narrowly won the state.
Fulton County district attorney Fani Willis in 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.
Under Trump, the Justice Department has also sued several states besides Georgia, demanding they turn over large volumes of voter data.
States have challenged the demands as an unconstitutional infringement on their authority to manage elections. A few judges have tossed out the lawsuits, most recently this week in Oregon.
A succession of people who have criticised Trump or resisted his agenda have found themselves investigated by the Justice Department, led by Trump appointee Pam Bondi, in the past year.
The department unsuccessfully tried to prosecute former FBI director James Comey and New York state Attorney General Letitia James, who both led previous investigations into Trump.
It also brought charges against former national security adviser John Bolton, a prominent Trump critic, and has opened investigations into nine Democratic lawmakers, a former CIA director and Federal Reserve chair Jerome Powell, who has resisted Trump's pressure to rapidly lower interest rates.
