World Politics
Background
At 4 p.m. Eastern on Tuesday 15 September, lawyers for the League of Women Voters and the Electronic Privacy Information Center are due to file their answer to one of the most consequential election-law questions the Supreme Court will handle before the 3 November midterms: whether the federal government may resume running the nation's voter rolls through an overhauled Department of Homeland Security database in order to check whether registered voters are US citizens.
The case is Department of Homeland Security v. League of Women Voters, No. 26A308, and it arrived on the court's emergency — or interim — docket on 8 September. Chief Justice John Roberts, who handles emergency applications from the District of Columbia, set the one-week response deadline that expires today. It is the second election-related application the Trump administration has brought to the justices in the space of three days, and the third major election case to reach them this month.
What SAVE Is, and What Was Changed
SAVE stands for Systematic Alien Verification for Entitlements. It is a long-standing DHS system built for a narrow purpose: letting federal, state and local agencies confirm an individual's immigration status when determining eligibility for public benefits. Historically it worked one query at a time and drew on immigration records.
That changed after an executive order signed by President Donald Trump on 25 March 2025, "Preserving and Protecting the Integrity of American Elections," which directed DHS and the Social Security Administration to build systems allowing state and local governments to verify the citizenship and immigration status of voters. The order also sought to impose a documentary proof-of-citizenship requirement for voter registration; several of its key provisions have been blocked in litigation. (Reporting also describes a second elections executive order issued on 31 March 2026 directing DHS, SSA and the State Department to compile "State Citizenship Lists" of confirmed citizens in all fifty states. Accounts differ on which order drives which component; the SAVE overhaul at issue before the justices traces to the 2025 directive.)
The agencies then rebuilt SAVE in three ways that matter. They added the records of US-born citizens, so the database was no longer limited to people with an immigration file. They gave it access to Social Security Administration records, including Social Security numbers. And they permitted bulk searches, so a state could submit an entire voter roll rather than inquiring about individuals. Together those changes converted a benefits-eligibility tool into an instrument capable of screening the entire American electorate.
How States Used It
Texas offers the clearest illustration of what bulk access looks like in practice. The Texas Secretary of State's office ran more than eighteen million registered voters through SAVE, identified 2,724 "potential noncitizens," and directed counties to investigate. That is a hit rate of roughly fifteen thousandths of one percent — and a flag is not a finding. In March 2026 voting-rights organisations including LULAC, Texas LULAC, LULAC Council 102 and Common Cause, represented by the Campaign Legal Center, sued the state, arguing that removals based on SAVE flags violate the National Voter Registration Act and that Texas had failed to cross-check proof of citizenship it already held in its own records before moving to strike voters. Local election officials in some counties had already removed flagged voters who did not respond to demands for documentation.
The District Court Ruling
On 22 June 2026, US District Judge Sparkle Sooknanan of the District of Columbia held that the modified SAVE system violated the Privacy Act, the Social Security Act and the Administrative Procedure Act, and barred the government from using it. Her language was unusually direct. "The federal government has knowingly trampled on the privacy rights of American citizens in a manner that threatens the sacred right to vote," she wrote. She went on to find that "states have partnered with the federal government to access the database and are actively removing United States citizens from voter rolls based on inaccurate information" — a factual finding, not a prediction, and the hinge on which the whole dispute turns.
The administration sought a stay pending appeal. Over the weekend of 5–6 September a divided panel of the US Court of Appeals for the District of Columbia Circuit refused to put Sooknanan's order on hold, while ordering the appeal itself to be fast-tracked.
The Government's Application
Solicitor General D. John Sauer filed on the morning of 8 September, calling Sooknanan's ruling an "indefensible order that threatens the integrity of upcoming elections by vacating the federal government's authority to internally use Social Security data when fulfilling its duty to respond to requests by States to verify the citizenship of individuals for voting and other purposes." The order, he told the justices, "makes it harder to detect ineligible voters, undermining the integrity of federal elections and public confidence in the results of those elections."
The government's lead argument is about standing rather than the merits. "SAVE does not disqualify any voter; instead, it merely notifies the States whether the federal government can confirm citizenship," Sauer wrote. "Thus, any voter injury is caused by the States, not by the federal government, and would not be redressed by the relief the court entered against the federal government." That framing would, if accepted, make the federal database effectively unreviewable in federal court: the government supplies the data, the states act on it, and the plaintiff is left suing whichever party did not do the thing complained of.
On the merits, Sauer argued that federal law requires DHS to provide citizenship verification and therefore authorises "steps — such as checking Social Security records — that are reasonably necessary to perform that duty," and that federal law bars courts from relying on the Privacy Act or the Social Security Act to block verification responses. On irreparable harm, he told the justices the government would be forced back to "an older, more cumbersome, and less reliable version" of SAVE, and that any eventual reversal on appeal "would come too late for the 2026 midterms."
The Wider Campaign
The database is one front in a much broader federal effort to obtain and act on state election data. Since May, the Justice Department has demanded election records from nearly every state and the District of Columbia — full statewide voter registration lists, ballots from previous elections, and in some cases access to voting equipment — and has sued states that refused. The exact tally varies by source and by date: CBS News has tracked 31 federal lawsuits seeking state voter data, while other accounts describe suits against 30 states plus the District of Columbia, of which 23 have been dismissed. Separately, on 1 September the Electronic Privacy Information Center, represented by Protect Democracy and Citizens for Responsibility and Ethics in Washington, filed suit challenging the effort to build "State Citizenship Lists" from federal databases, arguing the underlying data is too unreliable to determine who may vote.
The justices are simultaneously holding two other election cases. On 6 September the administration asked them to block an order by US District Judge Indira Talwani in Boston barring parts of a new Postal Service rule on mail-in ballots — U.S. Postal Service v. California, No. 26A305 — with Sauer arguing that the order "nullif[ies] the Postal Service's efforts to address the risk that the federal mails will be used to perpetrate voter fraud." And on 10 September the court granted an application preventing Missouri from using a 2025 Republican-drawn congressional map, leaving the state to run November's election on its 2022 lines.
The Factual Dispute Underneath
Both sides invoke election integrity, and they mean opposite things by it. The administration treats the risk as under-detection: ineligible registrations that go unnoticed dilute lawful votes. The challengers, and Sooknanan, treat the risk as over-detection: a database assembled at speed from records never designed for this purpose, flagging naturalised and native-born citizens as non-citizens and triggering removals that may not be corrected before a ballot is cast. Noncitizen voting in federal elections does occur, but investigations and audits have consistently found it to be very rare, and the claims of widespread instances that prompted the 2025 executive order have largely been debunked. The lower courts found the rebuilt SAVE was, in practice, too error-prone for the use to which states were putting it.
What's Next
Once the response is filed this afternoon the application is ripe. Roberts may act alone or, more likely given the stakes, refer it to the full court; a ruling on the interim docket could come within days. Whatever the justices decide will be provisional — the D.C. Circuit's expedited merits appeal continues regardless — but in practical terms it is close to final for this election, which is precisely the argument the Solicitor General made. The immediate question is whether states can run bulk citizenship checks during the final voter-registration windows, and whether county officials resume removing voters the system flags.
The broader development is institutional. With seven weeks to go, the rules governing how Americans will register, vote by mail and be counted in November are being set not by Congress or by full appellate argument but by emergency applications decided on compressed briefing, often without oral argument and sometimes without reasoning. Three such applications are live at once. However the SAVE case comes out, that pattern is likely to outlast it.
