In his top post at the Department of Homeland Security, David Harvilicz sets policy on protecting the nation’s elections infrastructure, including voting machines.He’s also the co-founder of a company with James Penrose, who helped hatch debunked conspiracy theories blaming hacked voting machines for Donald Trump’s loss in the 2020 presidential election. Penrose assisted in a push to seize voting machines to overturn Trump’s defeat.On social media, Harvilicz has called for doing away with voting machines, saying they are “eminently vulnerable to exploitation.” In a March post, he wrote that “DHS needs to ban voting machines for all federal elections. The time is now.” He also has repeatedly questioned the validity of Democratic electoral victories and pushed for Republicans to overhaul electoral systems to their advantage.Election experts as well as current and former DHS officials say Harvilicz’s central role in overseeing the security of electoral systems and voting machines is especially concerning at a time when the administration is taking unprecedented steps to relitigate Trump’s baseless claims that the 2020 election was stolen. That includes the FBI’s seizure of 2020 voting records from Fulton County, Georgia, and having a team working for Tulsi Gabbard, the director of national intelligence, take custody of voting machines used in Puerto Rico in 2020.“The security of our election infrastructure depends on leadership that is trusted, impartial and grounded in evidence — not individuals who have promoted conspiracy theories about the very systems they are now responsible for protecting,” said Danielle Lang, vice president for voting rights and the rule of law at the Campaign Legal Center, a nonpartisan pro-democracy organization. “Placing someone with that background in charge of policies affecting election security can undermine public confidence in our elections at a time when trust is already fragile.”DHS didn’t answer detailed questions about Harvilicz or his team, providing a more general statement about the work done by the agency. “DHS and its employees are focused on keeping our elections safe, secure, and free,” it said. “Every single day appointees at the Department of Homeland Security work to implement the President’s policies and keep our Homeland safe.”Harvilicz didn’t respond to questions about his DHS role. Harvilicz’s X account notes his post as DHS’ assistant secretary for cyber, infrastructure, risk and resilience policy but says he’s been detailed to the Defense Department. (Such temporary assignments are typically done in 120-day increments.)Harvilicz was appointed to the DHS job around July, taking on a role that in the past has largely focused on shaping policy to protect the nation’s critical infrastructure, including its election systems.But current and former DHS officials say Harvilicz and his team have transformed their functions to become more hands-on. They’ve been deeply engaged with facilitating multiple administration data-gathering efforts aimed at scouring voter rolls for noncitizens, the officials said. ProPublica has reported on one such effort, which has led to hundreds of citizens being incorrectly flagged as potential noncitizens.Harvilicz’s team includes Heather Honey, the deputy assistant secretary of election integrity. ProPublica has reported that Honey was previously a leader in the Election Integrity Network, a conservative group that has challenged the legitimacy of American election systems. Honey worked closely with Cleta Mitchell, the network’s leader, who played a prominent role in helping Trump try to overturn his 2020 loss.Also reporting directly to Harvilicz is Samantha Anderson, a data specialist who previously worked to elect Trump through the advocacy arm of the America First Policy Institute, a think tank closely associated with the president.Multiple officials and elections experts said they were worried that Harvilicz and Honey would have prominent parts in assessing and describing the cybersecurity of the coming election, both to the public and to administration leaders. They also expressed concern that if Trump again wanted to get control of voting machines after the election, perhaps if Republicans lose seats in the midterms, that Harvilicz is ideally positioned to help them do so.“It would be super easy for them to get the voting machines,” a current DHS official said, adding they can “describe it as they want, if they don’t like the results.”Harvilicz co-founded Tranquility AI, which has developed an artificial intelligence tool for law enforcement, with Penrose, and they are listed on its 2025 patents as developing its systems together.Penrose, a former intelligence officer, played a leading role in the campaign to help Trump in his failed bid to overturn the 2020 election, ProPublica has reported.
