US Supreme Court Revives Trump Administration Voter Citizenship Database

The U.S. Supreme Court on Friday allowed the Trump administration to resume using an expanded federal immigration database for citizenship checks on registered voters, reviving a program supporters say protects election integrity and opponents argue could wrongly remove eligible voters.

The justices granted the Justice Department’s request to block a lower-court ruling that had prevented state officials from using Social Security numbers and other federal records for large-scale citizenship verification. The court’s three liberal justices dissented.

The dispute centers on the Department of Homeland Security’s Systematic Alien Verification for Entitlements, known as SAVE. DHS redesigned the system in 2025 to permit bulk searches and checks using Social Security information. Under the modified program, information can be compared with Social Security Administration records to help determine citizenship status.

The Supreme Court majority said the challengers were unlikely to succeed on their claims, pointing to federal law that it said authorizes DHS to request and receive citizenship and immigration-status information from other government agencies.

Several Republican-led states have used the expanded SAVE system to compare federal information with voter-registration records. The Trump administration argues the database gives states an important tool for identifying noncitizens who may be improperly registered.

Voting-rights and privacy organizations, including the League of Women Voters and Electronic Privacy Information Center, challenged the program. They argue that inaccurate or outdated federal records could mistakenly identify naturalized U.S. citizens as noncitizens, potentially threatening eligible voters’ registrations.

A federal district judge in Washington had blocked the modified system in June, finding that its implementation violated federal privacy and administrative laws. The D.C. Circuit subsequently declined to suspend that decision while the administration appealed.

The Supreme Court’s latest order allows the modified SAVE program to operate while the broader legal dispute continues, putting the federal citizenship-verification system back into focus ahead of the November midterm elections.
