Supreme Court Allows States to Use Federal SAVE Database for Voter Eligibility Checks
By NewsPulse Staff | September 26, 2026
With the November midterm elections just over five weeks away, the U.S. Supreme Court voted 6-3 on Friday to let the Trump administration expand the use of a federal immigration database for checking voter eligibility — a decision that could shape how states maintain their voter rolls in the final stretch of the campaign.
The unsigned order lifts a block imposed in June by a federal district judge, clearing the way for states that choose to participate to resume using the SAVE system — the Department of Homeland Security's Systematic Alien Verification for Entitlements database — to verify whether registered voters are U.S. citizens.
What the SAVE system does
SAVE is a federal database states already use to check immigration status when determining eligibility for public benefits. Under the expanded use, election officials can check individual voter registrations against Social Security numbers and citizenship records, one person at a time.
At least 25 states have used the system since April 2025, running tens of millions of registrations through it, according to court filings. The Trump administration ordered the expansion in March 2025, arguing it would help identify noncitizens improperly on voter rolls.
The Court's majority reasoned that the federal government has a duty to answer state and local requests to verify whether voters are citizens. The order does not require any state to use the database — participation remains voluntary.
Why critics are worried
The D.C. district judge who originally blocked the expansion had concluded the citizenship data was unreliable and that eligible citizens could be wrongly flagged or removed. Voting-rights groups, including the League of Women Voters, along with privacy organizations, sued the Departments of Homeland Security and Justice and the Social Security Administration over the policy.
The three dissenting justices — Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson — argued that the risk to lawful voters outweighs the harm the government claims to be addressing. According to the dissent, officials in at least one Texas county told the Court that some people flagged by the system turned out to be U.S. citizens.
Federal law also restricts most systematic voter-roll removals within 90 days of an election, a safeguard designed to prevent last-minute purges. How that rule interacts with the expanded SAVE checks in the coming weeks is likely to be tested in court.
What happens next
The November 3 midterms will be the first major test of the expanded system. Supporters say it gives states a long-needed tool to keep voter rolls accurate. Critics say it risks disenfranchising eligible voters at the worst possible moment — right before an election.
Election administrators in participating states will now decide how aggressively to use the database in the limited time remaining. Voting-rights advocates say they will be watching closely for signs that eligible voters are being flagged, and further legal challenges are widely expected.
Separately, the Court was also asked this week to take up a case concerning whether immigrants held for deportation are entitled to bond hearings when detention stretches on — a sign that immigration law will remain a central battleground at the Court well beyond the midterms.
The bigger picture
The SAVE fight is part of a broader national debate over how aggressively states should police their voter rolls. Supporters of stricter checks point to public confidence: polls consistently show that large majorities of Americans favor requiring proof of citizenship to register to vote. They argue that a federal database built for exactly this kind of verification is the most reliable tool available.
Skeptics counter that documented cases of noncitizen voting are extremely rare, and that the greater danger lies in eligible citizens being caught in an imperfect system — especially when there is little time to fix mistakes before Election Day. Studies of past voter-roll maintenance efforts have repeatedly found that database mismatches, from typos to outdated records, are far more common than actual ineligibility.
With early voting set to begin in many states within weeks, election officials are under pressure to get this right. Whatever happens in November, the SAVE decision has ensured that the mechanics of American elections — not just their outcomes — will be under the microscope.
