Democrats File New Challenge Against Trump's Mail Voting Executive Order

Senate Minority Leader Chuck Schumer (D-N.Y.) and House Minority Leader Hakeem Jeffries (D-N.Y.) joined other congressional Democrats on May 21, 2026, to announce a renewed effort to block President Donald Trump’s executive order regarding mail voting. The Democrats argue that a newly finalized U.S. Postal Service (USPS) rule has addressed concerns that previously led to a judge rejecting their initial request for an injunction as premature. This new filing claims that the USPS lacks the authority to regulate mail ballot distribution and represents the first legal challenge to the order based on its merits. The Democratic Senatorial Campaign Committee (DSCC), Democratic Congressional Campaign Committee (DCCC), Democratic National Committee, Democratic Governors Association, Schumer, and Jeffries filed the supplemental complaint in their lawsuit in Washington, D.C., contesting Trump’s March executive order. They also submitted a renewed motion for a preliminary injunction, requesting a court hearing around September 4. The Democrats assert they are significantly harmed by what they describe as the President’s unlawful attempts to alter the electoral landscape to his advantage. This legal action follows a U.S. Supreme Court decision that lifted an injunction blocking parts of Trump’s order in 23 Democratic-led states and Washington, D.C., on the grounds that the challenge was premature. The Democratic plaintiffs contend their situation differs due to the USPS's new rule, which they argue directly impacts mail voting nationwide. In May, U.S. District Judge Carl Nichols, a Trump appointee, denied the Democrats’ initial request to block the order, stating that their challenge was not yet ripe since the USPS had not issued a final rule. The Democrats now claim that the USPS's final rule has resolved the previous uncertainties. The new rule mandates that ballot mail envelopes for federal elections meet specific design requirements, requires state election officials to submit voter-identifying information and barcodes to the USPS through an online portal, and allows the USPS to refuse to send ballot mail that does not meet these new standards. The plaintiffs argue that this rule could disproportionately affect Democratic candidates, as a higher percentage of Democratic voters utilize mail voting compared to Republican voters. They cite data indicating that 44% of Democratic candidates’ voters cast ballots by mail or absentee, compared to 26% of Republican candidates’ voters. The plaintiffs express concerns that voters may be disenfranchised if their names are not included on the USPS mail ballot list or if their ballots are delayed or rejected due to the new envelope requirements. They emphasize that voters have no means to verify their enrollment on the USPS list before it is too late. This renewed motion represents a continuation of the legal battle over Trump’s efforts to modify mail voting ahead of the 2026 midterms. Trump’s March executive order directed the USPS to propose new rules for mail ballots and instructed the Department of Homeland Security to create state citizenship lists, which Democrats initially criticized as an attempt to manipulate the electoral process. In their original lawsuit, Democrats argued that Trump’s order would limit access to mail voting and improperly involve federal agencies in election administration, a role they assert is constitutionally reserved for states and Congress. They are now reiterating these arguments against the final USPS rule, asserting that the Postal Service lacks the statutory authority to regulate mail ballot distribution. The plaintiffs contend that the rule violates the Constitution’s separation of powers, as election administration is the domain of states and Congress, not the President or the USPS. They are requesting that Judge Nichols issue a preliminary injunction to prevent the rule from impacting the midterms, arguing that once an election occurs, the opportunity for judicial intervention will be lost.
