On March 31, 2026, President Trump signed an executive order that lets the Postal Service refuse to deliver a mail ballot unless the voter is on a state-submitted list checked against new federal citizenship data — a rule aimed, the White House says, at people who shouldn’t be voting. It has now been blocked, unblocked, and blocked again by the same federal judge in the space of five months, with the Supreme Court weighing in once and Election Day six weeks out. Whatever rules apply to your mail ballot this November may still be changing as it arrives.
The order, titled “Ensuring Citizenship Verification and Integrity in Federal Elections,” does three things. Section 2 has the Department of Homeland Security build state-by-state lists of citizens, drawn from Social Security records, the SAVE database, and federal citizenship files, that states can check against their own voter rolls. Section 3 requires states to submit their approved mail-ballot lists to the Postal Service 60 days before a federal election; USPS will only deliver or collect ballots for voters on that list, using a uniform envelope design and tracking barcodes. Section 5 tells the Attorney General to prioritize prosecuting election officials who issue ballots to people the federal government considers ineligible, and threatens federal funding for states that don’t comply.
Twenty-four states and D.C. sued within days, and by late June, U.S. District Judge Indira Talwani had blocked the order for all of them. The 1st Circuit upheld her in July. She widened the block to cover every state on August 11. Then, on August 24, the Supreme Court’s Republican-appointed majority lifted that first injunction — not by ruling the order legal, but by ruling the challenge premature. The order noted, pointedly, that the decision “does not mean that any measure taken by the Government to implement the Order will necessarily be lawful.”
Two days later, Talwani read that reasoning as applying to her nationwide block too, and lifted it herself. Two days after that — August 28 — she blocked the Postal Service’s rule again, this time on different grounds: Congress, she wrote, never gave USPS the authority to regulate election mail. That freeze runs at least 14 days, with a hearing on a permanent injunction set for September 3.
The White House called the rules “commonsense measures that protect the security of mail-in ballots and ensure only Americans are electing American leaders.” Trump has said for years that significant numbers of noncitizens vote in federal elections; it’s already a federal crime, and researchers who study this have found documented cases are rare.
New York Attorney General Letitia James, leading a coalition of 25 Democratic state attorneys general, called the August 24 ruling “a painful setback” that “will not be the final word,” and said flatly: “USPS has no authority to decide who can and cannot vote by mail.”
Justice Ketanji Brown Jackson wrote the sharpest dissent of the group, arguing the majority had missed “the Government’s actual objective: to secure our imprimatur for its effort to foment chaos ahead of the November elections,” and flagging a catch-22 in the majority’s own logic — a challenge filed before implementation is premature, one filed after is too late to matter.
Election Day is November 3. Some states’ mail ballots go out within the next couple of weeks. States that would have to comply say they can’t redesign ballot envelopes, build a barcode-tracking system, and submit citizenship-checked voter lists to the Postal Service on that timeline — with no new federal funding to do it. The Postal Service itself said it wouldn’t move without Supreme Court clearance; a district court has since taken the decision out of its hands anyway, at least for the next two weeks.
Noncitizen voting is already illegal, and the administration’s underlying claim — that it’s a real if hard-to-measure problem — doesn’t require proof of scale to justify a fix; a system that verifies eligibility before a ballot goes out is preventive, not punitive. The Supreme Court’s majority didn’t uphold the order on the merits, but its procedural instinct is a real principle, not a dodge: a court blocking a federal rule before it’s even final, based on what a state fears the rule might do, skips a step the process is built around. And the Attorney General enforcing existing law against officials who knowingly issue ballots to ineligible voters is the Justice Department doing what it already has the power to do.
The Constitution puts elections in the hands of states and Congress — the Elections Clause names them specifically — and Judge Talwani’s second ruling doesn’t rest on politics; it rests on a specific, checkable fact: Congress never passed a law letting the Postal Service decide whose ballot gets delivered. Election-reform groups point to SAVE’s documented history of flagging citizens as noncitizens — a system built to verify immigration status for benefits, not to determine who votes — and note that a mistaken flag here doesn’t cost someone a form, it costs them a ballot. Critics also note the 60-day list deadline lands before many states’ own registration deadlines, meaning a late-registering voter can be shut out by the federal rule before their state’s own deadline even arrives. A rule that can’t be implemented without “Herculean” effort in the six weeks before an election isn’t security — it’s chaos with a deadline attached.
Both sides are arguing from real constitutional ground, which is part of why this keeps bouncing between courts instead of settling. The Elections Clause gives states the administrative role Judge Talwani is defending; nothing in it, or in any statute cited so far, gives the Postal Service veto power over a ballot. But the Supreme Court’s majority found the original challenge premature, not wrong — this fight is paused, not over, with a hearing on September 3 and Election Day counting down from there. What’s true either way: the rules for how your ballot gets handled this November are being written six weeks before it’s due, by three different courts, none of whom agree yet.
Berman’s history of the fight over who gets to vote, and who gets to make that harder, is the long version of the argument playing out in court this week.
