Supreme Court Lets Trump Use Social Security Data to Find Noncitizen Voters
The Supreme Court ruled Thursday to allow the Trump administration to use an expanded federal database linking Social Security records to state voter rolls to identify potential noncitizen voters, handing the administration a win less than six weeks before the November 2026 midterm elections. The unsigned order from the court’s conservative majority reversed a lower court decision that had blocked the program since June.
What the SAVE Database Does
SAVE stands for Systematic Alien Verification for Entitlements, a federal system that has existed for roughly 40 years. It was originally created to verify immigration status for individuals applying for public benefits such as Medicaid and housing assistance. The Department of Homeland Security overhauled the system by linking it to Social Security Administration records, which cover the vast majority of Americans, and by enabling states to submit entire voter rolls for bulk citizenship queries rather than individual lookups.
At least 26 states uploaded their voter lists to the expanded system. As of the ruling, SAVE had processed more than 67 million voter registrations and flagged approximately 28,635 individuals as potential noncitizens. Participation by states remains voluntary.
The Legal Battle
U.S. District Judge Sparkle L. Sooknanan blocked the modified SAVE system in June, ruling that the Department of Homeland Security lacked Congressional authorization to build what challengers described as a “master citizenship database.” She found the program violated the Social Security Act, the Privacy Act, and the Administrative Procedures Act. A federal appeals court upheld her decision before the Supreme Court intervened on Thursday.
The court’s majority sided with the administration without issuing a written opinion, which is standard for emergency orders of this type. The ruling came in response to a challenge brought by the League of Women Voters and the Electronic Privacy Information Center. It follows a series of immigration rulings in which the court has generally sided with the Trump administration’s enforcement priorities.
Justice Ketanji Brown Jackson authored a dissent joined by Justices Sonia Sotomayor and Elena Kagan. “The harm caused by burdening or disenfranchising even a few lawful voters outweighs the nonexistent harm that the Government experiences when it is prevented from taking an action that it likely lacks the authority to take,” Jackson wrote. She also flagged the risk that recently naturalized citizens could have their registrations wrongly canceled.
Evidence of Errors
Data from Texas illustrates the accuracy concerns surrounding SAVE. Officials there flagged 2,724 voters through the system; roughly 20 percent were later confirmed as eligible U.S. citizens who required reinstatement. Independent investigators found that between 10 and 21 percent of individuals flagged as noncitizens by the database were, in fact, American citizens.
Critics of the expanded system argue that even a small error rate, applied across tens of millions of records, could result in thousands of eligible voters being wrongly removed or burdened with the task of proving their citizenship before they can cast a ballot.
Practical Limits and What Comes Next
Despite the ruling, its near-term effect on voter rolls is limited. The National Voter Registration Act bars states from systematically removing voters within 90 days of a federal election. Because voting in the November 2026 midterms is already underway in some states, most cannot act on SAVE data to purge registrations before Election Day.
The administration has pointed to concerns about noncitizen voting alongside broader election fraud claims as justification for the expanded database, a position critics say is not supported by evidence of widespread abuse. Independent researchers have found that verified cases of noncitizen voting are exceedingly rare.
The ruling returns the case to lower courts, where the underlying legal questions about DHS’s authority remain unresolved. The Supreme Court’s order is not a final ruling on the merits; the challengers are expected to continue litigating. How the midterm elections affect the political landscape around voter verification legislation may determine whether Congress revisits the legal authority at the heart of the dispute.
