Trump signs second federal-elections executive order asserting presidential control over voter eligibility and mail voting

On March 31, 2026, President Donald Trump signed Executive Order 14399, "Ensuring Citizenship Verification and Integrity in Federal Elections." The order directs two federal agencies — the Department of Homeland Security (via its Systematic Alien Verification for Entitlements program) and the Social Security Administration — to build federal "citizenship verification" lists for use in determining who may vote in federal elections, and instructs the U.S. Postal Service to deliver mail ballots only to people who appear on those lists. The order purports to rest the authority for these directives on Article II of the Constitution and on existing federal voter-registration statutes.

This is the second elections-focused executive order of Trump's second term. The first, issued in March 2025, was substantially blocked by federal courts: in January 2026, D.C. District Judge Colleen Kollar-Kotelly held that "our Constitution does not allow the President to impose unilateral changes to federal election procedures." The Elections Clause (Art. I, Sec. 4) vests the regulation of federal-election "Times, Places and Manner" in the states, with Congress empowered to modify state rules. The Brennan Center, the Brookings Institution, NPR's election-law sources, and the coalition of state attorneys general that has filed suit all characterize the new order as duplicating the legal flaw of the first.

Twenty-four state attorneys general, joined by the Governor of Pennsylvania, filed for summary judgment to permanently block the order. Oregon Attorney General Dan Rayfield, who is part of that coalition, described the central issue: the executive order asks the U.S. Postal Service to act as an arbiter of voter eligibility, "and that's not a role the Postal Service was built for, not a power the federal government has, and not something Oregon will accept."

Beyond the constitutional question, the order's practical mechanism — restricting mail-ballot delivery to a federally maintained allow-list — creates a likely path to disenfranchisement of eligible voters whose records do not cleanly match DHS or SSA databases, a population that historically skews toward naturalized citizens, voters who have moved recently, and voters whose names differ slightly across records. The practical effect is voter suppression in addition to the structural overreach.

2026-05-28 — Judge declined to preliminarily block mail-ballot and citizenship-list provisions [6, 7]

U.S. District Judge Carl Nichols — a Trump appointee in Washington, D.C., and the first federal judge to rule on the order — declined to preliminarily block two of its central provisions: the Postal Service mail-ballot restriction and the Department of Homeland Security citizenship-list directive. He found the challenge premature because neither agency had yet acted to implement the order, leaving the plaintiffs (Democratic Party committees, nonprofit groups, and states) unable to show concrete harm. Nichols signaled the result could change once the agencies act, writing that plaintiffs "may, of course, renew their motions if and when those future actions occur." The consolidated case remains pending before him, and a separate challenge is pending in federal court in Boston.

2026-06-25 — Boston judge blocked the citizenship-list and mail-ballot provisions for the states that sued [8, 9]

U.S. District Judge Indira Talwani (District of Massachusetts) blocked the two central provisions of EO 14399 — the DHS and Social Security Administration "citizenship verification" list directive and the Postal Service mail-ballot restriction — as applied to the 23 states and the District of Columbia that brought the challenge, for the 2026 elections. Talwani found no statutory basis for the Postal Service's role, writing that "no law enacted by Congress delegates authority to control mail-in voting to USPS." She dismissed the plaintiffs' claims about future elections as not yet ripe, leaving open the possibility of later implementation.

2026-07-07 — Florida judge ordered DHS to restore the SAVE features a D.C. court had blocked, splitting the courts [10, 11]

U.S. District Judge T. Kent Wetherell II (Northern District of Florida) ordered the Department of Homeland Security to reinstate the SAVE database's bulk-upload and Social Security number search features for Florida, Indiana, Iowa, and Ohio, finding the agency had violated a prior settlement when it disabled them on June 23, 2026. The order directly conflicts with a June 22, 2026 ruling by U.S. District Judge Sparkle Sooknanan (District of Columbia) that the same features violated the Social Security Act and the Privacy Act. Acknowledging the split, Wetherell wrote that "one of the orders has to give, and not surprisingly, the Court is not persuaded by Defendants' ... arguments that its order is the one that should give," leaving two federal district courts in direct conflict pending appeal.

2026-07-17 — D.C. Circuit stayed a separate injunction, clearing USPS to advance a related ballot-barcode rule [12, 13]

A three-judge D.C. Circuit panel stayed U.S. District Judge Emmet Sullivan's injunction — issued in a long-running NAACP lawsuit under a 2021 USPS settlement — that had blocked the Postal Service from finalizing a proposed rule requiring states to supply voter lists and ballot-tracking barcode data to determine mail-ballot delivery. The panel found USPS made a strong showing it would succeed on the merits because the challenge was premature and the rule did not violate the settlement, letting USPS proceed toward finalizing the rule while the underlying appeal continues. The ruling is separate from Talwani's June 25 injunction, which still blocks the citizenship-list and mail-ballot provisions in the 23 states plus D.C. that sued over EO 14399 directly.

2026-07-25 — 1st Circuit upheld Talwani's injunction 2-1, blocking EO 14399 mail-ballot and voter-list provisions in 23 states [14, 15]

A three-judge panel of the U.S. First Circuit Court of Appeals denied the Trump administration's emergency motion to stay Judge Talwani's June 25 injunction, ruling 2-1 that the order blocking EO 14399's citizenship-list and mail-ballot delivery provisions in the 23 plaintiff states and D.C. would remain in effect. The majority found the administration failed to demonstrate a likelihood of success on the merits, writing that the order "directs unprecedented levels of involvement by federal officials in how states administer elections." Judge Joshua D. Dunlap, a Trump appointee, dissented in part. The ruling means the Postal Service may not condition mail-ballot delivery on appearance on a federal citizenship list in the states that sued.

2026-07-27 — DOJ asked Supreme Court to stay injunction and clear the way for EO 14399 [16, 17, 18]

U.S. Solicitor General D. John Sauer asked the Supreme Court to stay Judge Talwani's injunction and allow full implementation of Executive Order 14399, two days after the 1st Circuit Court of Appeals upheld the injunction blocking the order's citizenship-list and mail-ballot provisions in the 23 states and D.C. that sued. Sauer argued the lower court's block "impedes the President's ability to direct his subordinates" and requested an immediate administrative stay ahead of the November midterm elections.

2026-07-28 — D.C. Circuit called a related case unripe, splitting from the 1st Circuit [19, 20]

A three-judge D.C. Circuit panel — Judges Patricia Millett, Robert Wilkins, and Gregory Katsas — upheld a lower court's May 28, 2026 denial of a preliminary injunction in a separate Democratic National Committee suit against the same executive order, ruling the challenge unripe because the Department of Homeland Security and U.S. Postal Service had not yet acted, even while acknowledging "serious questions concerning the lawfulness" of the order if implemented. The ruling directly conflicted with the 1st Circuit's decision two days earlier upholding the injunction in the 23-state suit, and Justice Ketanji Brown Jackson, assigned to the 1st Circuit, ordered briefing on the Trump administration's emergency Supreme Court application due by August 3, 2026.

2026-07-29 — Twelve GOP-led states joined DOJ's emergency Supreme Court application [21]

Missouri, Alabama, Florida, Indiana, Kansas, Louisiana, Montana, Nebraska, Oklahoma, South Carolina, South Dakota, and Texas filed their own emergency Supreme Court application asking the Court to let EO 14399 take effect before the November midterms, joining the Department of Justice's stay request against Judge Talwani's injunction. The states argued, as DOJ had, that the injunction was premature because no federal agency had yet fully implemented a rule under the order. Justice Ketanji Brown Jackson directed the 23 Democratic states challenging the order to file a response by August 3, 2026.

2026-08-03 — States urged Supreme Court to leave injunction in place [22, 23, 24]

The 23 states and D.C. challenging EO 14399 filed their court-ordered response to the Supreme Court, urging the justices to reject the administration's and 12 Republican-led states' emergency applications to stay Judge Talwani's injunction. The states told the justices that granting a stay "would allow the federal government to rush out an unprecedented, legally indefensible voter-verification and ballot-interception program," warning that implementing the citizenship-list and mail-ballot provisions this close to the November midterms risked disenfranchising eligible voters and causing administrative chaos.

2026-08-11 — Judge expanded mail-ballot injunction nationwide in a separate suit [25, 26]

U.S. District Judge Indira Talwani granted a preliminary injunction in a separate lawsuit brought by the League of Women Voters and other voting-rights groups, expanding her June 25 block on the Postal Service's implementation of EO 14399 from the 23 states and D.C. that originally sued to every state nationwide for the 2026 midterm elections. Talwani found the groups were likely to prove the order exceeds presidential authority under the Constitution and was causing voter confusion, writing that "the executive branch has no authority to regulate elections" and that the approaching November 3, 2026 midterms "underscores the critical need for an injunction to prevent Defendants from changing election rules on the eve of the election." The ruling adds a further hurdle for the administration's pending request that the Supreme Court lift the original injunction.

2026-08-21 — USPS finalized mail-ballot restriction rule despite ongoing injunctions [27, 28]

The U.S. Postal Service published a 95-page final rule implementing EO 14399's mail-ballot restrictions, despite the Talwani and separate California injunctions currently blocking the changes from taking effect. The rule itself acknowledges both injunctions and states it is being finalized now so it can take effect immediately if a court lifts them, requiring states to give federal agencies voter lists and ballot-tracking data before USPS will deliver mail ballots for federal elections; USPS said it received more than 200,000 public comments on the proposal. The federal government has separately sued 30 states and Washington, D.C. for refusing to hand over voter lists.

2026-08-24 — Supreme Court stayed injunction blocking mail-ballot order in 23 states [29, 30, 31]

The Supreme Court stayed Judge Talwani's June 25 injunction that had blocked EO 14399's citizenship-list and mail-ballot provisions in the 23 states and D.C. that sued, granting the emergency applications the Trump administration and 12 Republican-led states filed. The unsigned majority opinion found the challenge premature because the order had not yet been implemented, rather than ruling on the order's legality; the Court's three Democratic appointees dissented, with Justice Ketanji Brown Jackson accusing the majority of missing "the Government's actual objective: to secure our imprimatur for its effort to foment chaos ahead of the November elections." A separate, broader nationwide injunction Talwani issued August 11 in a suit brought by the League of Women Voters and other groups was unaffected and continues to block the Postal Service from implementing the mail-ballot restriction. Solicitor General D. John Sauer had told the Court in a July filing that implementation "will need to begin well before November — indeed, as soon as early to mid-August — to be effective for the 2026 election."

2026-08-25 — Judge found administration violated nationwide mail-ballot injunction [32]

U.S. District Judge Indira Talwani found that the Trump administration violated the nationwide injunction she issued August 11 when the U.S. Postal Service published its final mail-ballot restriction rule on August 21, but imposed no immediate remedy, ruling only on the voting rights groups' motion to enforce her order and reserving the administration's separate motion to reconsider the injunction — filed after the Supreme Court's August 24 stay of Talwani's other, narrower injunction in the related 23-states case — for a later order. Talwani indicated the violation finding could ultimately benefit the plaintiffs by making the issue ripe for further relief even without an immediate remedy.

2026-08-26 — Talwani lifted her own nationwide mail-ballot injunction, removing the last block on EO 14399 [33, 34]

U.S. District Judge Indira Talwani lifted her own August 11 nationwide injunction against the Postal Service's implementation of EO 14399 — the last remaining block on the order — saying she found it "likely that the Supreme Court would apply the same reasoning" it used to stay her narrower, 23-state injunction two days earlier, while quoting Justice Jackson's dissent in a footnote. Talwani separately called the order's practical effect "likely unconstitutional" and warned it could cause "chaos," but said she was compelled to lift the block regardless. The ruling clears the way for the administration to implement the order's mail-ballot provisions ahead of the November midterms. Roughly two dozen Democratic-led states and the District of Columbia filed a new lawsuit against the Postal Service the same day, arguing the final rule's uniform-envelope and voter-list mandates are unworkable before ballots go out the following week.

2026-08-28 — Judge issued new 14-day block in refiled suit [35, 36]

U.S. District Judge Indira Talwani issued a new temporary restraining order blocking the Postal Service from implementing the mail-ballot restrictions for at least 14 days, in the suit voting-rights groups and roughly two dozen states plus D.C. refiled after the Supreme Court's stay of her narrower injunction. Talwani wrote that "the court is unaware of, and no party has proffered, any delegation Congress has made that would permit the USPS to regulate election mail," and that the government had not rebutted the states' claims that November compliance would be "impossible for many of them." A hearing on a permanent injunction is set for September 3, 2026.

2026-09-01 — Whistleblower alleged USPS continued mail-ballot system work despite the injunction [37]

A whistleblower disclosure provided to Sen. Richard Blumenthal and made public September 1 alleged the Postal Service was continuing "secretive, rushed" development of the digital mail-ballot barcode and verification system required by EO 14399, despite Judge Talwani's August 28 order blocking implementation. Blumenthal said the disclosure showed "the Postal Service has designed a system to disenfranchise millions of Americans," and began questioning Postmaster General David Steiner about the new online voter-ballot portal. The Postal Service did not immediately respond to a request for comment.

2026-09-03 — DOJ rushed an emergency Supreme Court application to enforce the mail-ballot rule [38, 39]

Solicitor General D. John Sauer filed an emergency application with the Supreme Court asking the justices to immediately let the Trump administration and Postal Service enforce EO 14399's mail-ballot restrictions, appealing Judge Talwani's August 27 temporary restraining order and her August 31 denial of a stay pending appeal -- before the 1st Circuit had ruled on DOJ's own pending stay request there. Justice Ketanji Brown Jackson, the circuit justice for the 1st Circuit, declined to grant an immediate administrative stay and instead ordered the 23-state coalition to respond by 10 a.m. September 8. The filing came two days after Sen. Blumenthal's whistleblower disclosure warning of a "substantial risk of a 'catastrophic failure'" in USPS's rushed implementation system.

2026-09-04 — USPS Inspector General opened a probe into the whistleblower's claims [40]

The U.S. Postal Service's Office of Inspector General opened an investigation into the whistleblower's allegations that the agency's mail-ballot verification system was rushed and could disenfranchise voters, days after House Democrats formally asked Inspector General Tammy Hull to do so. House Oversight Committee ranking member Rep. Robert Garcia said the inspector general's office confirmed it was "opening an investigation into the Trump Administration's attempt to undermine vote-by-mail." Postmaster General David Steiner acknowledged the whistleblower's claims but defended the system, saying USPS "stand[s] behind both the rigor of our process and the resulting system" while pledging to "continue to monitor performance."

2026-09-04 — Talwani converted TRO into preliminary injunction blocking mail-ballot rule through the midterms [41, 42]

U.S. District Judge Indira Talwani converted her August 27 temporary restraining order into a preliminary injunction, blocking the Postal Service's mail-ballot rule -- the envelope design review, unique tracking barcodes, and federal voter-data upload portal required under EO 14399 -- through the November 3, 2026 midterms and any federal elections before that date. Talwani found that complying with the rule by the midterms was "likely impossible" for election officials and held the rule unconstitutional where it intrudes on the Elections Clause powers Congress never delegated to the Postal Service. The ruling rendered the administration's pending appeal of the earlier restraining order moot; DOJ and the Republican-led intervenor states have since filed new appeals of the September 4 order to the First Circuit. Washington Secretary of State Steve Hobbs said the ruling keeps the state's midterm election procedures unchanged, with mail ballots set to begin going out October 16.

2026-09-05 — D.C. Circuit declined to revive DHS's overhauled SAVE database program [43]

A divided D.C. Circuit panel ruled 2-1 that the Department of Homeland Security forfeited its central arguments for reviving the SAVE database's citizenship-verification and Social Security number search features, finding DHS raised those arguments only after the district court had already granted summary judgment against it. The modified SAVE system remains disabled nationwide; a merits panel may still reconsider and the government can still appeal to the Supreme Court.

2026-09-06 — DOJ filed a third emergency Supreme Court application on the mail-ballot rule [44]

Solicitor General John Sauer filed a third emergency application asking the Supreme Court to overturn Judge Talwani's September 4 preliminary injunction blocking EO 14399's mail-ballot rule through the midterms, arguing mail ballots have already begun going out in North Carolina with more states to follow and that each day of the injunction is costly. The injunction remained in effect as of filing.

2026-09-08 — DOJ asked Supreme Court to restore SAVE database expansion [45, 46]

Solicitor General D. John Sauer filed a separate emergency application asking the Supreme Court to overturn the D.C. Circuit's September 4 ruling and restore DHS's expanded SAVE database plan, which cross-references Social Security data and lets states run bulk citizenship-verification searches. Sauer called the underlying order, from U.S. District Judge Sparkle Sooknanan, "indefensible," arguing it "threatens the integrity of upcoming elections." The Supreme Court ordered the voting-rights and privacy groups that sued to respond by September 15, 2026. This application is distinct from DOJ's separately pending emergency application on the mail-ballot rule.
