The Justice Department filed a lawsuit in a California federal court on Thursday, asking a judge to block the state from tallying ballots cast by people it says are likely non‑citizens in the upcoming midterm elections. The move follows a Tuesday delivery of an encrypted thumb drive to Los Angeles County officials containing more than 20,000 names and a demand that citizenship be verified within 48 hours. California’s top election officials have refused to comply, arguing the request is unlawful and threatens voter confidence.
The Legal Challenge
The suit, lodged in the central district of California, claims the DoJ supplied the state with a list of over 20,000 individuals suspected of being ineligible to vote. It asks the court to enjoin California from counting any vote‑by‑mail ballots from those names until their citizenship can be confirmed through independent verification. The filing argues that allowing such ballots to be tabulated risks diluting the votes of eligible citizens and undermines the integrity of the federal election.
State and Local Resistance
Los Angeles County Clerk and Recorder Dean Logan said his office would not review the list, citing concerns that the USB drive was not a secure method for transmitting sensitive data. In a statement, California Secretary of State Shirley Weber, a Democrat, denounced the DoJ’s actions as a relentless effort to obtain protected voter information and warned that it would only sow chaos and erode public trust in the electoral process.

Weber quoted the department’s request as “unlawful” and warned that complying would set a dangerous precedent for federal interference in state‑run elections.
Background on Voter‑Roll Allegations
The Justice Department’s move echoes earlier claims by the Department of Homeland Security, which earlier this year estimated as many as 278,000 non‑citizens could be on voter rolls in four states, including over 190,000 in California and roughly 16,000 in Nevada. When DHS shared a subset of 185 names with Nevada officials, an investigation found every individual to be a citizen, raising questions about the accuracy of the data and the methodology used to compile the lists. Election law scholar Richard Hasen of UCLA described the DoJ’s effort in California as “a nice publicity stunt that gets attention for the department and reinforces the notion among the president’s most ardent supporters that California is not doing enough to combat voter fraud.” He also noted that the National Voter Registration Act bars systematic purges of ineligible voters in the 90‑day period before an election, a safeguard designed to prevent the removal of eligible voters who are mistakenly flagged.
Why it Matters
The lawsuit highlights a growing partisan flashpoint over election security, with federal officials seeking to assert authority over state voter rolls while state leaders warn that such actions risk disenfranchising legitimate voters and damaging public faith in the democratic process just weeks before a consequential midterm contest. The outcome could shape how future disputes over voter eligibility are resolved and influence the broader debate on election integrity across the United States.
