The Supreme Court sided with the Trump administration Friday in a 6-3 decision allowing the federal government to use an expanded citizenship database to help states verify voter eligibility, a ruling opponents say could affect millions of registrations before the midterms.
Six conservative justices granted the administration's emergency request to restore access to the Systematic Alien Verification for Entitlements program, known as SAVE, after lower courts had blocked the government from modifying the decades-old system. The unsigned ruling reversed a federal district court injunction and a D.C. Circuit appeals court decision that found the administration's expansion of the database was likely unlawful. NBC News reported the ruling came down along strict ideological lines, with all three liberal justices dissenting.
The decision hands the White House a significant legal victory in its push to ensure only American citizens appear on state voter rolls ahead of the November 2026 midterm elections. It also sets up a direct clash between the administration's election-integrity agenda and civil-rights groups who argue the database is riddled with errors that could burden lawful voters.
The SAVE program dates to 1986, when Congress created it so government agencies could check the immigration status of benefits applicants. Under President Trump's March 2025 executive order, which directed agencies to take steps to better ensure only U.S. citizens vote, the Department of Homeland Security expanded the system by folding in Social Security Administration records. That expansion enabled Social Security number searches and allowed states to upload voter lists in bulk rather than running one-at-a-time queries.
At least 25 states have voluntarily used the expanded system since April 2025, scanning more than 67 million voter registrations, the New York Post reported. Several Republican-led states had already begun comparing voter lists and canceling registrations of flagged potential noncitizens before the lower courts stepped in.
The League of Women Voters and allied groups challenged the expansion, arguing it violated the Social Security Act and the Privacy Act. A federal district court, presided over by Judge Sparkle L. Sooknanan, agreed and blocked the program. The D.C. Circuit upheld that injunction.
The Supreme Court majority found otherwise. In its per curiam opinion, the Court stated that federal law "requires the government to respond to requests from states for information about citizenship" and that the lower court order "prevents the federal government from using the program it believes is best suited to the task." The six Republican-appointed justices concluded that the challenging groups' claims that the SAVE modifications violated federal privacy statutes likely lacked merit.
James Percival, General Counsel at the Department of Homeland Security, captured the administration's frustration in a statement after the ruling. As Reuters reported, Percival said:
"Yes, you read that right. We had to file an emergency petition in the Supreme Court just so we could use government data to help states stop noncitizens from illegally voting."
Solicitor General D. John Sauer had argued in court papers that the district court's injunction "threatens the integrity of upcoming elections." Just The News detailed the administration's petition, in which Sauer called the lower court ruling "indefensible."
Jason Snead, executive director of the conservative Honest Elections Project, welcomed the outcome. He said the expanded database "just makes it easier for states to get federal citizenship data to help them clean up voter rolls."
The ruling marks a reversal from the Court's recent 7-2 defeat of the administration on mail-in ballot rules, suggesting the justices are drawing careful lines between different election-administration disputes rather than siding reflexively with or against the White House.
Justice Ketanji Brown Jackson wrote the dissent, joined by the Court's two other liberal members. She argued the majority was enabling a program the government likely had no authority to operate in its expanded form:
"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."
The League of Women Voters echoed that concern, issuing a statement that the ruling "puts millions of Americans at risk for being unlawfully targeted by the administration's unreliable voter purge database."
Those fears are not entirely abstract. Texas was one of the first states to run its full voter rolls through the expanded SAVE system, processing more than 18 million registrations. Reporting by ProPublica and The Texas Tribune found that many of the flagged registrants were newly naturalized citizens and that local election officials noticed mistakes in the database's results.
Yet the actual enforcement numbers tell a different story about the scale of the problem opponents describe. After running those 18 million-plus registrations through the system, Texas authorities charged just three people with voting illegally as a noncitizen. Three, out of 18 million.
The majority acknowledged that the National Voter Registration Act, the federal law that governs how states maintain their rolls, bars broad purging of voter registrations in the weeks leading up to an election. The Court said this existing safeguard "limits the potential impact" of the ruling for the 2026 cycle. States can still make individualized queries about specific voters, but mass removals close to Election Day remain off-limits under federal law.
That distinction matters. The administration's supporters frame the SAVE expansion as a routine data-sharing upgrade, giving states access to federal records they need to do the list-maintenance work that federal law already requires. Opponents frame it as an invitation to error-prone purges that will disproportionately burden naturalized citizens who have every right to vote.
The Trump administration's relationship with the Supreme Court has been mixed this term, with wins on some executive-power questions and losses on others. Friday's ruling falls squarely in the win column and gives the White House its preferred tool heading into a consequential midterm season.
Several open questions remain. It is unclear which specific justices beyond Jackson dissented, whether additional concurrences were filed, or what procedural steps a flagged voter must take to prove citizenship and stay on the rolls. The ruling also does not specify whether other states beyond the 25 already participating plan to adopt the system before November.
For the administration, the math is straightforward: federal law requires states to maintain accurate voter rolls, and the government built a tool to help them do it. For opponents, the Texas experience, where 18 million checks produced three prosecutions and an unknown number of bureaucratic headaches for lawful citizens, illustrates the gap between the program's stated purpose and its practical effect.
The Court's recent election-related docket shows the justices are willing to engage on these disputes case by case. And with major rulings reshaping the political landscape in rapid succession, the stakes of each decision only grow as November approaches.
The government should not have to beg the courts for permission to share its own citizenship records with the states charged by law with keeping voter rolls clean. That it took an emergency petition to the nation's highest court to restore that basic function says more about the legal resistance than it does about the database.
