Judge Halts DHS Voter Fraud Probes in Nine States Citing Flawed Data

A federal judge has ordered the Department of Homeland Security to halt field operations investigating noncitizen voting in nine states, ruling that the administration’s efforts rely on flawed data and intimidate eligible voters ahead of the Nov. 3 midterms.

The Ruling

U.S. District Judge Araceli Martínez-Olguín issued a preliminary injunction barring DHS agents from conducting interviews or home visits targeting individuals who are U.S. citizens or where citizenship status is uncertain. She found that the agency’s use of unreliable data likely violated the Voting Rights Act by creating an "objectively reasonable fear" among citizens, chilling their participation in the election. The order applies to California, Connecticut, Georgia, Missouri, Nevada, New York, Pennsylvania, Washington, and Wisconsin, and remains in effect through Election Day unless appealed.

Data Accuracy Disputes

The core conflict centers on the reliability of the lists used to identify potential fraud. Los Angeles County officials analyzed a sample of the Justice Department’s list of 20,000 alleged noncitizens and found that 38.9% were born in the United States and 71.2% had no voting history. Judge Martínez-Olguin noted that without a federal database confirming citizenship, the risk of error is high, especially when agents are given only 12 minutes per review during "surge" phases. While DHS maintains it is focused solely on removing aliens who vote, critics argue the lists are built on bad data and have already led to the wrongful identification of naturalized citizens.

Political Context

This legal battle is part of a broader war between the Trump administration and California over election integrity. The DOJ has sued to block ballots from the flagged list and charged 28 green card holders with voter fraud. Meanwhile, Democratic leaders and voting rights groups have filed separate lawsuits alleging the administration is using these probes to sow doubt and seize control of elections. DHS spokespersons insist they have no plans to investigate U.S. citizens, but plaintiffs say the aggressive tactics have already caused intimidation.
