The FBI search of election offices in Fulton County, Georgia, that led to the seizure of ballots from the 2020 election was ordered by Kurt Olsen, who previously helped President Donald Trump challenge his loss in that election and is now working for the Trump administration.

The revelation comes from an affidavit filed by the FBI and disclosed on Tuesday. That affidavit led a judge to authorize the Jan. 28 raid on Fulton County election offices in order to investigate whether election officials in the county illegally altered or tampered with the 2020 election results in a manner that could have cost Trump the election.

On Election Day in 2020, Trump immediately claimed that fraud led to his loss to Democrat Joe Biden, a claim that has since been exhaustively disproven. Nevertheless, he mounted a nonstop public and legal campaign to overturn the results. Much of this effort focused on Georgia, where he attempted to pressure Secretary of State Brad Raffensperger, a Republican, to “find 11,780 votes,” the exact number needed to put Trump ahead of Biden. Raffensperger did not oblige. No fraud was found in Georgia or any other state, and Trump eventually pivoted to trying to block the certification of Biden’s win, culminating in the Jan. 6 insurrection and his second impeachment.
