In brief

On Oct. 15, 2026, the U.S. Justice Department filed a federal complaint against California over its voter rolls. The department said analysis with Homeland Security partners found more than 20,000 registrants who are likely noncitizens, and that state officials declined to remove them or sequester related mail ballots.

According to the Justice Department press release, federal law bars noncitizens from voting in federal elections, and California mails a ballot to every registered voter. Officials said Homeland Security Investigations compared public registration files with immigration data and that the review is ongoing.

Attorney General Todd Blanche and DHS Secretary Markwayne Mullin framed the suit as protecting election integrity. The Central District of California U.S. Attorney's office said the state was given a chance to act on a federal list and refused. California's response in court will determine next steps; the complaint's claims have not been ruled on.

NPR and other outlets also reported the administration is seeking to block counting of mail ballots tied to the disputed list ahead of November elections. Readers should treat the figures as allegations in litigation until a court decides.

Why it matters

The case could affect how states verify voter eligibility and handle mail ballots weeks before a national election.
