When President Donald Trump attempted to overturn the 2020 election, the institutional guardrails of American democracy held — but just barely.
If faced with the same tests today, those guardrails and the people who held the line would largely be missing, a ProPublica examination found.
At least 75 career officials who once held roles at federal agencies related to election integrity and safety are gone. Two dozen appointees — including many who either actively worked to reverse the 2020 vote or are associates of such people — have been hired to replace them. And once-fringe actors now have access to vast powers.
As the midterms approach, current and former government officials and election security experts expressed concerns that Trump appointees who’ve espoused debunked conspiracy theories about balloting are now in positions to control the narrative around the vote’s soundness.
It’s hard to debunk false claims “coming with the seal of the federal government,” said Derek Tisler, counsel and manager with the Brennan Center for Justice’s elections and government program. “I certainly worry what damage that could do to voters’ confidence.”
Here are some of the key things you should know about the Trump administration’s efforts to, as the president said, “take over” the midterms. Read the full investigation here.
1. In 2020, institutional guardrails helped to prevent Trump from overturning the election.
Following his defeat in the 2020 election, Trump pushed for federal officials to uncover proof that he had, in fact, beaten Joe Biden at the polls. Election cybersecurity experts with the Department of Homeland Security relayed to Attorney General William Barr that the election fraud claims that they looked into were false. Barr then told the president what he didn’t want to hear: The election had not been hacked.
Barr was one of many federal officials — most of them Trump appointees — who refused to bend to the president’s demands, which only intensified in the weeks leading up to Jan. 6, 2021. Despite the violent uprising at the Capitol on that day, the election results held firm.
2. Less than 18 months into his second term, Trump has dismantled many of those same guardrails.
Since the start of his second term, Trump and his appointees have made significant changes at federal agencies tasked with helping to safeguard elections. In all, at least 75 career officials who’d played important roles in elections work at DHS, the Department of Justice and other agencies have left, been fired or been reassigned, ProPublica found.
In their place are roughly two dozen people Trump has installed in positions that could affect elections. Ten of them actively worked to reverse the 2020 vote, and the rest are associates of those people. In some cases, ProPublica found, officials have been hired from activist groups that are pillars of the election-denial movement.
3. Among the first agencies Trump gutted after returning to office was one that had repeatedly disproved his stolen-election claims.
Officials at DHS’ Cybersecurity and Infrastructure Security Agency had provided research to the first Trump White House that disproved many theories claiming that the 2020 election had been hacked. CISA also played a crucial part in publicly countering these claims by producing a “Rumor Control” website to rebut them.
Then, only weeks into Trump’s second term, DHS leadership put employees focused on countering disinformation and helping safeguard elections on leave. They also froze CISA’s other election security work, which included assessing local election offices for physical and cybersecurity risks. Eventually, all CISA employees specializing in elections were fired or transferred.
A DHS spokesperson told ProPublica that the changes at CISA were in response to “a ballooning budget concealing a dangerous departure from its statutory mission,” which included “electioneering instead of defending America’s critical infrastructure.”
4. Trump and his appointees have gutted election-related teams at federal law enforcement agencies.
FBI Director Kash Patel dismantled the agency’s public corruption team, which had previously been deployed to help monitor possible criminal activity on Election Day. The Foreign Influence Task Force, which aimed to combat foreign influence in U.S. politics, was also disbanded.
(An FBI spokesperson said the bureau “remains committed to detecting and countering foreign influence efforts by adversarial nations.”)
The voting section of the DOJ’s Civil Rights Division had enforced federal laws that protect voting rights, particularly those that combat racial discrimination. But now, nearly all of the section’s roughly 30 career lawyers have resigned or been moved. Trump then filled the section with conservative lawyers, including at least four who participated in challenging the 2020 vote or have worked with people who helped Trump try to overturn the 2020 election.
5. Trump has replaced ousted career specialists with “Team America.”
In the summer of 2025, after the Trump administration had forced out most of the career specialists, a small group of political appointees — which once called itself “Team America,” according to sources familiar with the matter — began convening at DHS headquarters, looking for federal levers it could pull to realize a March 2025 executive order, in which Trump tried to exert greater federal control over aspects of voting.
Among the core members of the group was David Harvilicz, a DHS assistant secretary tasked with overseeing the security of election infrastructure, including voting machines, and three of his top staffers. As ProPublica has reported, Harvilicz co-founded an AI company with an architect of Trump’s claims about election hacking in Michigan.
Heather Honey, who serves under Harvilicz in a newly created position focused on elections, is a source of the false claim that more ballots were cast in Pennsylvania than there were voters in the 2020 presidential election — a claim Trump cited on the morning of Jan. 6, 2021.
At least 11 administration appointees, including Honey, have ties to the Election Integrity Network, a conservative grassroots organization led by Cleta Mitchell, a lawyer who tried to help Trump overturn the 2020 election. Since moving into government, Honey has maintained close ties to Mitchell’s organization, and she and at least two other federal officials have given its members private briefings.
6. Team America members are using a powerful Homeland Security Investigations tool to try to identify noncitizen voters.
The DOJ has been demanding that states turn over confidential voter roll information, and it has sued around 30 states for this data.
Meanwhile, DHS has urged states to upload their voter rolls to its tool, called the Systematic Alien Verification for Entitlements system.
The goal in both efforts has been to find noncitizens on the voter rolls. But the SAVE tool has come up short, often identifying citizens as noncitizens, as ProPublica has reported, and officials have faced other roadblocks with its use.
More recently, according to two people familiar with the matter, Team America has worked to harness a more powerful tool used by another branch of DHS, Homeland Security Investigations, to increase its ability to search for noncitizen voters and bring criminal charges against them.
In response to questions sent to DHS, Harvilicz and Honey, a DHS spokesperson disputed that they were seeking to use the department’s powers to advantage Trump. In response to questions about their ties to the election denial movement, the spokesperson wrote, “To meet the diverse and evolving challenges the Department faces, we hire experts with diverse backgrounds who go through a rigorous vetting process.”
7. Trump’s head of election security is behind the FBI’s seizure of 2020 election ballots in Georgia.
Attorney Kurt Olsen once worked to try to overturn Trump’s 2020 loss in court and was later sanctioned by judges for making baseless allegations about Arizona elections. He is now Trump’s director of election security and integrity and is the driving force behind the January raid of the election center in Fulton County, Georgia.
Toward the end of 2025, Olsen flew to Georgia to meet with Paul Brown, the head of the FBI’s Atlanta field office, according to people familiar with the matter. Olsen wanted the FBI to seize ballots from the Democratic stronghold, and he gave Brown a report he claimed would justify the extraordinary action. Brown’s team submitted an affidavit to superiors at the DOJ that did not make a strong enough case to move forward with what Olsen wanted. Afterward, Brown was given a choice: retire or be moved to a new office. Brown retired. The raid went forward under his replacement, based on an affidavit that cited information from the report Olsen provided to Brown.
Olsen did not respond to requests for comment.
An FBI spokesperson said that Brown “elected to retire” and that its “work in the election security space is entirely consistent with the law.”
8. The DOJ’s Public Integrity Section could have tried to block the administration’s Georgia voting investigation.
In the months following Trump’s return to office, the DOJ’s Public Integrity Section, which had been responsible for making sure the department’s inquiries weren’t improperly influenced by politics, was eviscerated. Resignations, firings and transfers reduced the 36-person section to two.
Multiple former lawyers for the section said they likely would have tried to block the Fulton County investigation because it lacked strong evidence, had a clear political slant and went against department directives that actions should not be taken “for the purpose of giving an advantage or disadvantage to any candidate or political party.”
John Keller was principal deputy chief of the section from 2020 to 2025 and was acting chief when he resigned in early 2025. He worries that allegations of irregularities in the upcoming election will be handled on a partisan basis.
“Without that review and without apolitical, objective, honest brokers involved in the process, there is a much greater risk for intentional manipulation or inadvertent interference,” Keller said.
