Justice asks the Supreme Court to let Homeland Security use its immigration database to purge state voter rolls

What happened

The SAVE system was originally designed to help states check the citizenship status of people applying for government benefits, and the administration has tried to turn it into a system for monitoring state voter registration lists. District Judge Sparkle Sooknanan's June 22 order found that the modified system violated federal privacy laws, the Social Security Act and the federal laws governing administrative agencies, and barred the government from using it; she wrote that "the federal government has knowingly trampled on the privacy rights of American citizens in a manner that threatens the sacred right to vote." A divided panel of the D.C. Circuit then turned down the administration's request to put that order on hold while the appeal moves forward, but directed that the case be fast-tracked. Before the order took effect the administration had used the database to check the citizenship status of more than 67 million registered voters; those checks flagged thousands of people as potential noncitizens, and further investigations found most were actually eligible voters. After the order went into effect the administration shut the database down for use as a voter registration list citizenship checker. The application is docketed as No. 26A308, Department of Homeland Security v. League of Women Voters, submitted to the Chief Justice on September 8, 2026; the Chief Justice requested a response from the challengers the same day, due by 4 p.m. EDT on September 15, 2026. Homeland Security Secretary Markwayne Mullin had earlier this year threatened state election chiefs with criminal charges if they do not use the SAVE program to check their voter rolls.

In the application the Solicitor General, John Sauer, calls the lower court's ruling "indefensible" and says it "threatens the integrity of upcoming elections", and the application states that 27 States have agreed to use the modified SAVE system to check the voter rolls. The expansion at issue is what the challenged order stopped: DHS added new sets of data to the programme, including Social Security records, and allowed states to upload their voter lists in bulk, where before the changes states could only run individualised checks of a single voter's citizenship status. Voter-roll audits using SAVE have been on hold in most of the country since the ruling. The request reaches the court while the administration is already pressing it to reinstate new Postal Service mandates for mail voting at the midterms.

Why it matters

The order under appeal did not decide who may vote; it decided which federal instrument may be pointed at state registration lists. Seeking to lift it on the emergency docket is an attempt to get that instrument back into service in the weeks before a federal election, the point at which a voter wrongly flagged has the least time to correct the record. What this record follows is the route rather than the result: whether a federal citizenship database becomes a working input to state purges.
