A federal judge has blocked the Department of Homeland Security from conducting election-related field operations and interviews under its Unlawful Voter Initiative in nine states, ruling that the tactics risk intimidating eligible voters and rely on flawed data. District Judge Araceli Martínez-Olguín of California issued the order Wednesday, blocking operations that involve or are likely to involve U.S. citizens. The ruling is a significant check on the Trump administration's efforts to investigate suspected noncitizen voting less than two weeks before the midterm elections.

District Judge Araceli Martínez-Olguín on Wednesday curbed the Trump administration's field investigations into suspected noncitizen voting across nine states. Her order blocks the Department of Homeland Security from conducting election-related operations and interviews that involve or are likely to involve U.S. citizens, and from carrying out operations based on records generated by the agency's voter-matching policy.

The judge wrote that the groups that sued provided 'substantial evidence' that the government's 'intimidating conduct' was 'directly interfering with their members' right to encourage voters to participate in the 2026 midterm elections.' She expressed doubt about the accuracy of the administration's data, noting that 'there is no federal database containing citizenship status of U.S. residents' and warning of 'a high likelihood of error in review.'

Court filings indicated that officers had been ordered to prioritize probes in California, Connecticut, Georgia, Missouri, Nevada, New York, Pennsylvania, Washington and Wisconsin. A whistleblower report released last month by Democratic Senators Chuck Schumer and Alex Padilla alleged that officials had diverted fraud and national security personnel to the initiative using 'highly questionable data' and methods. The report claimed officers were directed to access voter information in violation of state laws under minimal training and significant pressure.

The administration defended its approach. A DHS spokesperson said the department is 'laser focused on identifying, prosecuting, and removing aliens who vote and dilute the votes of U.S. citizens,' adding that it has 'no plans to question or investigate people we believe to be U.S. citizens.' In court, the administration argued that it 'reasonably decided to make use of the best data it had available to it to perform its law enforcement role, notwithstanding that the information may not be perfect in all cases.' It also contended that the allegations of voter intimidation were too vague.

The ruling comes as courts have repeatedly blocked the Trump administration's attempts to obtain state voter data. Last week, the administration sued California over claims that suspected ineligible voters received mail-in ballots, asking a court to delay about 20,000 ballots from being counted. On Tuesday, Democratic groups filed a separate lawsuit accusing the government of using unfounded fraud claims to interfere in election administration.

Analysis

Why This Matters

The ruling directly curtails a central part of the Trump administration's election integrity efforts with midterms less than two weeks away.
It highlights ongoing disputes over data accuracy in identifying noncitizen voters and the potential for voter intimidation.
The decision could affect how DHS conducts future investigations and sets a precedent for judicial oversight of federal election-related enforcement.

Background

The Trump administration has repeatedly sought to investigate suspected noncitizen voting, which is rare. Courts have previously blocked efforts to access state voter rolls. The administration's data has been criticized as inaccurate. The Unlawful Voter Initiative directed resources to this area. A whistleblower report raised concerns about methods and diversion of personnel. This ruling is the latest in a series of legal battles over election administration.

Key Perspectives

[DHS/Trump Administration]: Defends the initiative as focused on preventing illegal voting. Argues it is using best available data and has no intention of investigating citizens. Views the court's ruling as an impediment to law enforcement. [Plaintiffs/Election Rights Groups]: Contend that the administration's tactics are intimidating and based on flawed data that risks disenfranchising eligible voters. Provided evidence of interference with voter encouragement efforts. [Federal Judge]: Found substantial evidence of intimidation and serious doubts about data accuracy, leading to restrictions on field operations involving likely citizens.

What to Watch

Whether DHS appeals the ruling or seeks to modify it ahead of the midterms.
