Whistleblower Says DHS Officers Raised Concerns Over Voter Data Searches

An anonymous whistleblower has alleged that Department of Homeland Security (DHS) officers raised concerns internally about the legality and reliability of a program directing them to search state voter registration databases and compile federal records on suspected noncitizen voters, according to a report published Monday by The Guardian.

According to the whistleblower, DHS lawyers advised officers involved in the effort that they would not be held responsible for potentially violating state laws governing access to voter registration information. The whistleblower said officers also expressed concerns about the reliability of the data being used to identify suspected noncitizen voters.

The initiative is part of a broader push by the Trump administration to investigate noncitizen voting ahead of the 2026 midterm elections, the report said. Instances of noncitizen voting are rare, and the administration's expanded investigative effort has so far identified only a small number of cases, according to the report.

The Guardian reported that the whistleblower's account raises questions about the legal basis for the searches and the accuracy of the underlying voter data used in the federal investigation. The report did not specify further details about the whistleblower's identity or position within DHS.

DHS has not yet publicly responded to the specific allegations detailed in the whistleblower's account, according to the report.
