But under President Donald Trump, U.S. Citizenship and Immigration Services dramatically expanded the system’s capabilities.
The changes allowed states to compare voter-registration information with federal records, including citizenship and Social Security data, in an effort to identify registrations that may require further investigation.
That expansion quickly became a major part of the administration’s election-integrity push.
By November 2025, states had reportedly submitted more than 46 million verification requests through the upgraded system.
Texas went particularly big, checking roughly 18 million registered voters and identifying 2,724 people as suspected noncitizens requiring additional review.
North Carolina also entered into an agreement with USCIS to use the federal system.
Then came the courtroom showdown.
Biden-Appointed Judge Strikes Down Expanded System
U.S. District Judge Sparkle Sooknanan, who was appointed by former President Joe Biden and confirmed by the Senate in December 2024, issued a sweeping 75-page decision on June 22, 2026, blocking the expanded SAVE operation.
Sooknanan concluded that the government’s use of Social Security information alongside citizenship records ran afoul of federal privacy and administrative laws.
Her ruling effectively dismantled a key component of the Trump administration’s nationwide voter-verification strategy.
“The federal government has knowingly trampled on the privacy rights of American citizens in a manner that threatens the sacred right to vote,” Sooknanan wrote.
The administration sought emergency relief while it continued appealing the decision.
But a divided panel of the U.S. Court of Appeals for the D.C. Circuit refused to put Sooknanan’s ruling on hold.
Trump-appointed Judge Gregory Katsas dissented.
Katsas argued that the federal government was likely to prevail on the merits and pointed to a separate federal ruling in Florida that he said conflicted with the D.C. court’s approach.
As for individuals potentially flagged by the verification process, Katsas wrote that they “simply have to provide proof of citizenship.”
That left the Trump administration with one obvious place to go: the Supreme Court.
Trump Administration Calls Lower-Court Ruling “Indefensible”
Solicitor General John Sauer has now asked the nation’s highest court to intervene.
His characterization of the lower-court decision was unmistakable.
He called the ruling “indefensible.”
According to Sauer’s filing, the district court’s order goes far beyond protecting individual records. The administration argues it prevents the federal government from efficiently using information already in its possession to help states determine whether people on their voter rolls are U.S. citizens.
And the timing could hardly be more consequential.
The November 2026 midterm elections are rapidly approaching.
Sauer warned that the injunction “threatens the integrity of upcoming elections.”
For Republicans, that argument lands amid continuing cases involving noncitizens accused or convicted of illegally participating in American elections.
Illegal Voting Cases Keep Emerging
The controversy isn’t occurring in a vacuum.
Authorities around the country have pursued cases involving foreign nationals accused of registering or voting illegally.
A Filipino national in Hawaii was charged over allegations that she illegally voted in the 2022 election and a 2024 primary.
Two Pakistani nationals in New Jersey were indicted in a case involving alleged fraudulent voting in a federal election.
A Chinese student attending the University of Michigan also surrendered to authorities after allegedly registering and casting a ballot during the 2024 general election.
In Florida, three noncitizens originally from Cuba, Haiti, and Brazil admitted to knowingly voting in federal elections.
Another particularly striking case involved a Colombian woman in Massachusetts who was convicted in connection with identity theft, passport fraud, and illegal voting during the 2024 presidential election.
Surveillance footage reportedly captured her wearing an “I Voted” sticker.
Individual prosecutions do not establish that noncitizen voting is widespread enough to change election outcomes. But Republicans argue that these cases demonstrate why states should have access to federal tools capable of identifying potentially ineligible registrations before ballots are cast.
The administration’s position is straightforward: if federal databases can help states verify citizenship accurately, Washington should not prevent states from using them.
Critics see a very different danger.
They argue that sweeping database comparisons can produce false matches, expose sensitive personal information, and potentially place eligible American voters at risk of being improperly challenged or removed.
That conflict — election integrity on one side and voter privacy and access on the other — is now sitting before the Supreme Court.
The Clock Is Ticking Toward November
The stakes are amplified by the calendar.
With the D.C. Circuit unwilling to suspend Sooknanan’s order, the Supreme Court could determine whether the expanded verification system returns before Americans vote in the 2026 midterms.
Republicans contend there is little justification for preventing states from checking questionable registrations against federal citizenship information.
Democrats and voting-rights advocates counter that federal agencies cannot disregard privacy protections simply because an election is approaching.
The Supreme Court now has an opportunity to decide whether the Trump administration can restart one of its most aggressive election-verification initiatives while the underlying litigation continues.
For Trump and Republican officials pushing voter-roll reviews, the decision could determine whether states regain access to the expanded SAVE system before Election Day.
For opponents, it could determine whether a controversial federal data-matching operation remains sidelined.
Either way, the dispute has moved far beyond one Biden-appointed district judge.
It is now in the hands of the nine justices — with the midterm clock already ticking.
