Supreme Court Clears Path for Trump Administration's Expanded SAVE Database in Voter Citizenship Checks

On September 25, 2026, the U.S. Supreme Court issued a per curiam opinion staying a lower court ruling that had blocked the Trump administration from using a revamped version of the Systematic Alien Verification for Entitlements (SAVE) database to help states verify voter citizenship. In a 6-3 decision, the majority found that claims by voting rights groups and privacy advocates likely lacked merit, citing congressional authorization under the 1996 Illegal Immigration Reform and Immigrant Responsibility Act (IIRIRA) for the Department of Homeland Security (DHS) to obtain citizenship and immigration data from agencies like the Social Security Administration (SSA). The ruling permits the federal government to assist states with individualized verification requests ahead of the November midterms, though it noted limits on mass purges under the National Voter Registration Act.

The case originated from a June 2026 order by U.S. District Judge Sparkle Sooknanan, who vacated the 2025 SAVE updates— which integrated SSA data and enabled bulk searches—finding they violated privacy laws and risked disenfranchising citizens. A federal appeals court upheld the block before the Supreme Court intervened. Justice Ketanji Brown Jackson dissented, joined by Justices Sonia Sotomayor and Elena Kagan, arguing the changes exceeded statutory limits and that potential voter harm outweighed government interests.

States like Texas have already used the system, identifying thousands of potential noncitizens among registered voters. DHS and Republican-led states supported the administration's position, emphasizing election integrity, while critics highlighted risks of errors in the data.
