The Supreme Court cleared the Trump administration to use a federal citizenship database for voter eligibility checks ahead of the midterms, reversing a lower-court block that had stalled the effort.
Six conservative justices ruled Friday that the Department of Homeland Security may resume using the Systematic Alien Verification for Entitlements system, known as SAVE, to run individualized checks on voter status. The unsigned opinion reversed a D.C. district court order that had barred the program.
The fight centers on a core election rule: only U.S. citizens may vote in federal contests. President Trump’s March 2025 executive order pushed federal agencies to help states keep noncitizens off the rolls. SAVE, a 40-year-old benefits database, was expanded for that work.
Post wires reported the high court held that the federal government has a duty to answer state and local election officials who ask for citizenship verification. The justices said the lower-court order stopped the government from using the tool it judged best suited to the job.
At least 25 states have already used SAVE on a voluntary basis since April 2025. Officials have scanned at least 67 million registrations, mainly in red states. The Nov. 3 midterms are the near-term test of whether cleaner rolls follow.
D.C. U.S. District Judge Sparkle L. Sooknanan blocked DHS from using SAVE in a 75-page June ruling. She wrote that Congress built protections “to prevent precisely this type of centralized data bank.”
Sooknanan accused the administration of having “haphazardly combined and repurposed the private information of millions of Americans, including citizenship data that they knew to be unreliable.” She said states were “actively remov[e] United States citizens from voter rolls based on inaccurate information.”
The League of Women Voters, the Electronic Privacy Information Center, and five unnamed U.S. citizens sued DHS, the Justice Department, and the Social Security Administration. They claimed the revamped SAVE system violated privacy and voting rights.
Travis County, Texas, officials filed an amicus brief urging the Court to reject the administration’s appeal. County staff investigated 97 voters flagged by SAVE and said at least 11 were U.S. citizens. The state of Texas filed its own brief defending the database.
The Supreme Court majority stressed the limited scope of what it restored. DHS may use SAVE “to conduct individualized inquiries,” the opinion said, with the emphasis in the original. The Court also warned it is already too late in the 2026 cycle for mass purges of voter rolls by state and local officials.
That line matters. The ruling is a win for election integrity tools, not a green light for last-minute wholesale removals. States still must follow their own notice and cure rules.
Fox News reported the emergency order temporarily allows the expanded SAVE effort to proceed so states can check citizenship eligibility while the larger case moves forward. Michael Morley, director of the Election Law Center at Florida State University, said the order lets the federal government share citizenship-status information it already holds to help officials register eligible voters and block improper noncitizen additions.
Jason Snead, executive director of the Honest Elections Project, called the SAVE expansion a major win for election integrity because it makes federal citizenship data easier for states to obtain when they clean their rolls.
The same Court has faced repeated clashes over Trump-era election and immigration rules, including earlier coverage of federal voter-roll screening and related emergency docket fights.
Justice Ketanji Brown Jackson wrote the dissent, joined by Justices Elena Kagan and Sonia Sotomayor. Jackson argued the harm from burdening or disenfranchising even a few lawful voters outweighs what she called a “nonexistent harm” to the government when it is blocked from an action she said it likely lacks authority to take.
That framing treats citizenship verification itself as the threat. The majority treated noncitizen ballots, and the states’ duty to stop them, as the live problem.
National Review noted the 6-3 decision in Department of Homeland Security v. League of Women Voters revived the expanded database aimed at noncitizen voting. Dan McLaughlin wrote that the case involved a strained reading of federal law designed to restrain Trump, and that the conservative majority rejected it on the emergency docket as midterm ground rules took shape.
Administration filings said DHS kept using Social Security data in certain cases even while SAVE was blocked, to verify information and help determine whether illegal voting may have occurred. In August, DHS launched its own probe to find noncitizen voters on state rolls and said the work was being handled “diligently and professionally.” A whistleblower alleged the effort was rushed and error-prone; DHS rejected that attack.
How SAVE works in practice is straightforward. The system was built decades ago to keep government benefits from going to noncitizens. After the March 2025 order, DHS added natural-born citizens to the register and allowed bulk searches with names, birthdays, and Social Security numbers instead of only agency-issued ID numbers. States then queried the system against their registration files.
Similar high-court skirmishes have marked the run-up to the midterms, from mail-in ballot executive order fights to other emergency stays on election procedure.
The decision restores a federal-state information channel. It does not invent a new federal power to rewrite state voter lists from Washington. Election administration remains a state job. Federal data is a support tool when states ask for it.
Critics still warn valid voters could be flagged in error, pointing to Travis County’s sample of 97 hits and 11 confirmed citizens. Supporters answer that a flag is a lead for local review, not an automatic purge, and that leaving noncitizens on the rolls is the larger integrity failure.
The Court’s own timing note undercuts panic on both sides. Mass removals this close to Nov. 3 are already off the table under ordinary election calendars. Individualized checks and future-cycle cleanup are the realistic path.
Trump-era cases keep returning to the same institutions. Separate dockets have covered criminal alien detention disputes and other immigration enforcement fights that also turned on federal authority and state cooperation.
Another track of election litigation has tested mail-ballot rules, including when the Court left a mail-ballot injunction in place over pointed disagreement on the bench.
For voters, the practical stakes are simple. States that want citizenship confirmation now have a restored federal database to query. Groups that sued to keep that channel closed lost at the highest court, at least while the appeal proceeds.
GOP lawmakers have also had to manage public tension with the Court itself in other settings, including when senators defended the justices and the Fed during separate institutional clashes. The SAVE order shows the conservative majority still willing to police lower-court blocks on Trump election directives.
Citizenship is not a paperwork nicety. It is the bright line between a national election and an open invitation. The Court just put the verification tools back in the hands of the officials charged with guarding that line.
