The FBI agents arrived at David Bolter’s Milwaukee home on a cool, cloudy Wednesday morning in late May. They were armed with a list of questions for the 2020 poll worker, who had raised concerns about the way local officials handled the 2020 election, Bolter told Votebeat.This article was originally published by Votebeat, a nonprofit news organization covering local election administration and voting access.President Donald Trump relied on Bolter’s claims in an unsuccessful 2020 lawsuit that sought to throw out more than 220,000 votes. That would have been more than enough to move Wisconsin’s 10 electoral votes from Democrat Joe Biden, who won the state, to Trump. Though courts, several election reviews, and many audits rejected Trump’s claims, the Republican never stopped believing that he was cheated out of the presidency in 2020.That appears to be why, last month, the FBI sent agents back to Milwaukee to question Bolter as part of an expanding national effort by the second Trump administration to investigate long-debunked claims of fraud in the 2020 election. The investigation into the 2020 election appears to be relying on already disproven allegations from people like Bolter. Bolter declined to divulge more about his conversation with the FBI, which has not been previously reported, but allegations from Bolter’s 2020 affidavit were central to some conspiracy theories about the 2020 election. For example, he alleged that somebody in Milwaukee’s absentee ballot counting facility announced around midnight on Election Day that a “huge truckload of ballots” was going to be delivered — an accusation for which there has so far appeared to be no additional evidence.Around the same time Bolter says he talked to the FBI, two plainclothes agents with FBI badges showed up at the apartment of a former Milwaukee resident and 2020 poll worker about an affidavit she submitted, according to the former poll worker, who asked to be identified only by her first name, Christine, to give her the freedom to discuss an ongoing investigation. Christine had also submitted an affidavit about the 2020 election, saying election workers had been told that all votes were counted, but she then saw workers continuing to count ballots around midnight. That affidavit was the focus of the agents’ questions, Christine told Votebeat.“I suspected wrongdoing, but I’m not saying that it actually happened,” she said. “I’m just one lowly person that was working there.”During the interview, she added, an agent showed her a photograph of Claire Woodall, the former Milwaukee election chief, asking her if she recognized the former election official who has been central to false allegations about the 2020 election. She identified her by name. Woodall didn’t respond to a request for comment.Caroline Clancy, a spokesperson for the FBI’s Milwaukee office, declined to comment.While investigators seem mainly focused on the 2020 vote, some elections experts believe the Trump administration’s wide-ranging probe is actually designed to create more doubts among Americans about future elections, as Republicans face strong political headwinds that could cost them control of Congress later this year.“This isn’t about the 2020 election, this is about the 2026 and 2028 elections,” said David Becker, executive director of the nonpartisan, nonprofit Center for Election Innovation and Research. “This is about intimidating election officials. This is about creating a stream of disinformation designed to delegitimize an election the president may believe he’s going to lose. This is designed by the president’s underlings to satisfy the unrealistic expectations of a president that still cannot comprehend that he lost an election that he definitely lost, and it’s incredibly destabilizing.” Wisconsin is the latest known target of the Trump administration’s 2020 investigation. The FBI is looking to interview elections officials and Milwaukee police officers in what some worry could be a precursor to an effort to seize ballots from the 2020 presidential race, as it already has in Georgia.The Trump administration is revisiting allegations of election fraud that have been repeatedly scrutinizedIn January, federal investigators seized 600 boxes of ballots from the 2020 election in Fulton County, Georgia. The heavily Democratic county, home to Atlanta, was key to Biden’s narrow 2020 victory in the state. As in Wisconsin, the FBI in Georgia has built its investigation on allegations that have already been repeatedly scrutinized by audits, investigations, and courts without unearthing any evidence of fraud or tampering that could have overturned the results.The Georgia search represented an unprecedented intervention by the federal government into local administration.
