Supreme Court clears Trump to use citizenship database for voter checks despite accuracy concerns
Eligible US citizens risk wrongful removal from electoral rolls, potentially disenfranchising voters ahead of midterm elections.
The harm to even a few lawful voters outweighs preventing an action the government likely lacks authority to take
Mark
So the Supreme Court just said states can use this database to check if voters are citizens. What's the actual problem here?
Mimi
The database flags people as non-citizens, but it gets it wrong. In Texas, at least 10 percent of the people flagged were actually U.S. citizens. And we're talking about this happening weeks before an election, when there's no time to fix mistakes.
Luke
But hold on—how many people are we actually talking about? Texas flagged 1,930 people total out of 18 million voters. That's a tiny fraction.
Mimi
True, but the concern is scale. Twenty-seven states use this system now. And the Supreme Court just removed the main legal barrier that was stopping it.
Mark
What was the barrier?
Mimi
A federal judge ruled the expanded database violated privacy rights and was illegal. The Supreme Court overruled that on Friday.
Luke
On what grounds?
Mimi
They said a 1996 law gives the Department of Homeland Security the authority to share citizenship data with states that ask for it. The conservative justices said the lower court decision was preventing the government from using what it believes is the best tool for the job.
Mark
And the three liberal justices disagreed?
Mimi
Strongly. Justice Jackson wrote that wrongly removing even a few eligible voters from the rolls is worse than preventing the government from using a tool it might not even have the authority to use in the first place.
Luke
So what happens now? Can states just start purging voters?
Mimi
Not in the weeks right before the election—the Supreme Court said the Voter Registration Act prevents broad purges then. But states can check individual voters one by one.
Mark
And if someone gets flagged by mistake?
Luke
That's the gap. We don't know how many states will actually use this aggressively, or how many eligible voters will end up removed before they realize what happened.
The Pulse
- The Supreme Court's six conservative justices overrode two lower court rulings to revive a controversial federal citizenship database, weeks before midterm elections.
- The SAVE database — expanded by the Trump administration to draw on Social Security records — has already flagged eligible U.S. citizens as non-citizens in Texas, with error rates reaching at least 10 percent in some counties.
- Justice Ketanji Brown Jackson's dissent cut to the core: even a handful of wrongfully disenfranchised lawful voters represents a harm that outweighs any government interest in an action it may not even have the authority to take.
- A partial guardrail remains — the National Voter Registration Act bars sweeping purges in the final weeks before an election — but states may still challenge voters individually, leaving millions in uncertain territory.
- Voting rights organizations warn the ruling puts millions at risk and vow to continue legal challenges, while some state officials, like Georgia's Brad Raffensperger, insist their vetting processes protect eligible voters from wrongful removal.
In a nation where the right to vote has long been treated as both promise and battleground, the Supreme Court's conservative majority has cleared the way for a federal database — built to verify citizenship for public benefits — to be turned toward the voter rolls. The decision overrides a lower court's finding that the system violated Americans' privacy and threatened their right to vote, invoking a 1996 law to grant states access to Social Security-linked citizenship data. With midterm elections approaching and documented errors already surfacing in states like Texas, the ruling raises an enduring question: how a democracy weighs the fear of illegitimate votes against the certainty of legitimate ones lost.
The Supreme Court's conservative majority cleared the way this week for the Trump administration to deploy a federal database — originally designed to verify citizenship for public benefits — as a tool for flagging suspected non-citizen voters across state lines. The system, known as SAVE, was dramatically expanded last year to allow bulk searches drawing on Social Security records, and 27 states have already begun using it.
A federal judge appointed by President Biden had ruled the expanded program illegal in June, finding that the government had knowingly violated the privacy rights of American citizens in ways that threatened the right to vote. A federal appeals court let that ruling stand. The Supreme Court's six conservative justices overrode both decisions on Friday, citing a 1996 law they said authorizes the Department of Homeland Security to share immigration and citizenship data with requesting states. The three liberal justices dissented, with Justice Ketanji Brown Jackson arguing that disenfranchising even a small number of lawful voters causes harm that far exceeds any government interest at stake.
The practical stakes are grounded in documented error. In Travis County, Texas, at least 10 percent of voters flagged as non-citizens turned out to be U.S. citizens. Since Texas began using SAVE, only three non-citizen voters have been charged with illegal voting — a figure that stands in sharp contrast to the hundreds of thousands the Trump administration has claimed are on the rolls.
The ruling does carry one limitation: the National Voter Registration Act bars broad voter roll purges in the weeks immediately before an election, which the majority cited as a check on the decision's near-term impact. States may still investigate voters individually, however. Georgia Secretary of State Brad Raffensperger told the BBC that his office interviews flagged voters before taking any action, insisting that guardrails prevent wrongful removals.
Voting rights groups were not reassured. The League of Women Voters, which led the legal challenge, called the ruling a disaster and warned that millions of Americans face unlawful targeting by an unreliable system with midterms weeks away. What remains to be seen is how aggressively states will act — and whether the database's known error rate will translate into eligible voters losing their place on the rolls before they have the chance to cast a ballot.
The Supreme Court's conservative majority cleared the way this week for the Trump administration to use a federal database to identify voters suspected of being non-citizens, overturning a lower court's decision that had blocked the system on privacy grounds. The database, called SAVE—Systematic Alien Verification for Entitlements—was originally created in 1986 to verify citizenship status for people applying for public benefits. But last year, the Trump administration expanded it dramatically, allowing bulk searches using sensitive information pulled directly from Social Security records. The result is a tool that can now flag voters across state lines, and 27 states have already begun using it.
In June, a federal judge named Sparkle L Soonnan, appointed by President Biden, had ruled the expanded system illegal. She found that the federal government had "knowingly trampled on the privacy rights" of American citizens "in a manner that threatens the sacred right to vote." A federal appeals court let that ruling stand. But on Friday, the Supreme Court's six conservative justices voted to override both decisions, citing a 1996 law that they said gives the Department of Homeland Security the authority to share citizenship and immigration data with states that request it. The three liberal justices dissented. Justice Ketanji Brown Jackson wrote that "the harm caused by burdening or disenfranchising even a few lawful voters outweighs the non-existent harm that the government experiences when it is prevented from taking an action that it likely lacks the authority to take."
The practical concern is straightforward: the database makes mistakes, and those mistakes can erase eligible Americans from the voter rolls. In Travis County, Texas, officials found that of nearly 100 voters flagged as non-citizens, at least 10 percent—and possibly more—were actually U.S. citizens. Since Texas began using SAVE last year, only three non-citizen voters have been charged with illegally voting in the state. By contrast, when Texas Governor Greg Abbott announced removals from the rolls in 2024, he cited 1,930 people removed out of nearly 18 million registered voters—figures far smaller than the hundreds of thousands of non-citizen voters that Trump and the Department of Homeland Security have claimed are on the rolls.
The Supreme Court's decision does include one constraint: the National Voter Registration Act prohibits broad purges of voter rolls in the weeks immediately before an election, which the majority said limits the "potential impact" of the ruling ahead of the midterms. But states can still check the citizenship of individual voters one by one. Some states, like Georgia, have worked closely with the government to implement SAVE. Georgia Secretary of State Brad Raffensperger, a Republican, told the BBC that his office thoroughly vets the government data, even interviewing flagged voters to confirm their status. "There's always guardrails in place, to make sure that we never denied the right to vote," he said.
Voting rights groups called the ruling a disaster. The League of Women Voters, which led the legal challenge, said the decision "puts millions of Americans at risk of being unlawfully targeted by the administration's unreliable voter purge database weeks before the midterm elections." The group said it would continue fighting to restore the district court's decision. The Trump administration has long maintained that SAVE is both lawful and necessary to prevent non-citizens from voting. What remains unclear is how aggressively states will use the tool in the coming weeks, and whether the documented error rate will translate into actual voters being wrongfully removed from the rolls before they can cast ballots.
