The Department of Homeland Security gathered more than 99 million records while investigating suspected voter fraud and examined nonprofit voter-registration groups in several states, according to internal reports from May and June released this month. The reports from Homeland Security Investigations, an agency within Immigration and Customs Enforcement, say the agency obtained 48.4 million records from independent sources and drew on another 50.6 million from the Justice Department. They do not specify what the records contained. A June 1 report says HSI reviewed 82 nongovernmental organizations in Pennsylvania. The agency also examined groups in Michigan, Minnesota, New Jersey and Ohio, and considered whether to use undercover agents to investigate organizations it suspected of registering noncitizens or encouraging them to vote. The report describes a plan to assess whether undercover personnel could support field investigations. It also says research on about 41 New Jersey organizations found “no derogatory information,” as did reviews of 20 nonprofit funds connected to a Washington, D.C.-based charitable foundation. The Pennsylvania chapter of the Council on American-Islamic Relations was flagged for further investigation, the report says. The group’s Pennsylvania executive director, Ahmet Selim Tekelioglu, said its voter-registration program follows applicable rules and is intended to help Muslim Americans participate in civic life. Education Minnesota, an educators’ union, was among 22 organizations HSI said it was beginning to research. Union president Monica Byron said the group learned of the inquiry through the document release and shared concerns about government surveillance of lawful voter-registration work. She said the union would continue encouraging eligible members to vote. The reports also say 26,563 records derived from ICE had been prioritized for further review, with attention to Michigan, Minnesota, New Jersey, Ohio and Pennsylvania. HSI sent records to its Innovation Lab for additional analysis and identification of what the report called high-value targets. Justice Department records were prioritized for review in those states as well as Arizona, California, Florida, Georgia and Texas. The records offer a view of the Trump administration’s election-fraud investigations ahead of the November midterms. They show federal investigators pursuing possible noncitizen voting and scrutinizing groups involved in voter registration, even as studies have consistently found that noncitizen voting is rare. About 154 million people voted in the 2024 presidential election, according to the U.S. Census Bureau. DHS said HSI investigates allegations of unlawful voter registration or voting by noncitizens in federal elections. The department declined to discuss specific investigations or methods, but said it was committed to investigating election fraud and ensuring that only U.S. citizens elect the country’s leaders. Democracy Forward, which obtained the records through a public-records request, said they raised concerns about the scale of the government’s effort and its implications for lawful civic activity. CAIR and Education Minnesota both said they would continue their voter-engagement work. The reports do not establish that the organizations under review engaged in illegal activity. They also do not explain the contents of the millions of records HSI analyzed. The documents show the investigations were active while federal and state officials were debating how to identify noncitizens on voter rolls and how much authority the federal government should exercise over elections.
