The United States Department of Homeland Security (DHS) threatened on 17 July to withhold federal election funding from states that do not comply with its demands to scrutinise voter registration lists, and warned that election officials could face fines or imprisonment. Secretary Markwayne Mullin told reporters that DHS had preliminarily identified approximately 250,000 noncitizen registrations across California, New Jersey, Nevada, and Pennsylvania, though he did not detail the methodology or provide evidence for the figures. The announcement followed a prime-time address by President Donald Trump in which he alleged, without substantiation, that American election systems remain vulnerable to foreign interference and fraud.

Viewed from Washington, the administration’s position is that mandatory security enhancements are necessary to restore public trust. Mullin said states must join the Systematic Alien Verification for Entitlements (SAVE) programme and scrub their rolls, or lose reimbursement grants for running federal elections. He also urged Congress to pass the SAVE America Act, which would require documentary proof of citizenship to vote. The four targeted states pushed back. California Governor Gavin Newsom’s office stated that voter fraud is extremely rare and that the administration had provided “no evidence” for its claims. Nevada Secretary of State Francisco Aguilar called the numbers “highly speculative” and said DHS had not shared proof. Pennsylvania’s top election official, Al Schmidt, said the state follows all federal laws and that noncitizen voting is exceedingly uncommon. New Jersey did not immediately respond.

The practical implications extend beyond the immediate funding threat. A federal judge in Delaware recently blocked DHS from repurposing the SAVE database for voter verification, ruling that it violated privacy laws and had inaccurately flagged naturalised citizens. Election law experts in the United States note that past reviews have found noncitizen voting to be vanishingly rare, and that the administration’s methodology remains opaque. The DHS has also said it will scrutinise ballots for votes cast by deceased individuals, another form of fraud that studies show is statistically negligible. The agency is working with the Commerce Department on security requirements and has given states two weeks to confirm cooperation.

The confrontation unfolds as the November midterm elections approach, with the president’s party facing the prospect of losing one or both chambers of Congress. Trump has for years asserted, without evidence, that the 2020 election was stolen, and his administration has moved to centralise control over election administration—firing officials at the Cybersecurity and Infrastructure Security Agency and the Election Assistance Commission, and suing states for voter data. The SAVE Act remains stalled in the Senate, where Majority Leader John Thune has said Republicans lack the 60 votes needed to overcome a Democratic filibuster. The states’ responses are due within two weeks, and further legal challenges are expected if the administration attempts to enforce the threatened penalties.
