Supreme Court lets Trump use modified SAVE voter database

The Supreme Court on Friday cleared the Trump administration to use a modified centralized database to verify voters' citizenship, pausing a federal judge's order that had blocked it. The unsigned seven-page opinion issued 39 days before the 3 November 2026 election said the lower court's order "inhibits the Federal Government's efforts to assist state and local agencies in the proper administration of the midterm elections."rollcall.com+1

The decision matters because it reverses a June ruling that had found the modified database violated federal privacy laws, the Social Security Act, and administrative law. The Supreme Court also agreed the challengers have standing to sue, citing a League of Women Voters member registered in Louisiana whose Social Security records do not show her as a naturalized citizen. The majority noted federal law limits mass voter roll changes near an election, but states can still run individualized searches.theguardian.com

What the order paused

The dispute began in late March, when President Donald Trump issued an executive order directing the Department of Homeland Security and the Social Security Administration to set up systems letting state and local governments verify voters' citizenship and immigration status. The agencies modified the Systematic Alien Verification for Entitlements database, known as SAVE, to include records of U.S.-born citizens, add access to Social Security numbers, and allow multiple simultaneous searches.

The League of Women Voters and the Electronic Privacy Information Center challenged the changes in federal court in Washington. On June 22, U.S. District Judge Sparkle Sooknanan ruled the modified SAVE system violated federal privacy laws, the Social Security Act, and administrative law, and barred the government from using it. She wrote that the federal government "knowingly trampled on the privacy rights of American citizens" and that states were removing citizens from voter rolls based on inaccurate information.

How the database was changed

Justice Ketanji Brown Jackson dissented, joined by Justices Sonia Sotomayor and Elena Kagan. She called the decision a "questionable interim ruling" about two statutory provisions the Supreme Court "has never before interpreted," and said the majority disregarded harms to lawful voters. She wrote that burdening even a few lawful voters outweighs the government's claimed harm when it is prevented from an action it likely lacks authority to take.

Jessica Huseman, editorial director of Votebeat, said the SAVE database was built to track noncitizens the Department of Homeland Security knows about, not a complete list of everyone in the country. She said states can now batch-search voter rolls, where previously they could search only one person at a time, and that the system returns significant errors, including mismatch problems reported repeatedly in Texas.

Where the errors showed up

Errors have surfaced in state data. The Department of Homeland Security wrongly identified 185 people on Nevada's voter rolls as non-citizens, state officials said. In July, Trump said DHS had found 278,000 non-citizens across Nevada, California, Pennsylvania, and New Jersey; follow-up letters said there could be as many as 278,000, including up to 15,903 in Nevada. In August DHS confirmed only 185 in Nevada, and on Wednesday state officials said all 185 were US citizens.

The National Voter Registration Act requires a 90-day period before a federal election during which voters cannot be removed from rolls, which limits the database's impact this cycle. Huseman said county election administrators remain responsible for removing voters and typically apply second-level checks before anyone flagged is removed. Democratic Congressional Campaign Committee chair Suzan DelBene called the ruling "a lever for Republicans to pull to misinform and scare away legal voters."
