Courts Block Trump Administration's Mail-In Voting Rule Ahead of Midterms

President Donald Trump issued an executive order directing changes to U.S. Postal Service mail ballot handling ahead of the 2026 midterm elections. The plan was challenged in federal court, and U.S. District Judge Indira Talwani in Boston temporarily blocked the rule from taking effect. In a September 3, 2026 hearing, Judge Talwani considered whether to extend that block, noting that the Postal Service had not provided her court with details on how it intended to implement the mail ballot regulations; the hearing occurred the day before the first state began sending mail ballots to voters. A second federal judge, in Washington, D.C., separately issued an order freezing the mail ballot rule, according to reporting around September 14, 2026, with the case expected to reach the U.S. Supreme Court. The Supreme Court subsequently rejected the Trump administration's attempt to restrict mail-in voting ahead of the midterms, according to NBC News reporting from September 14, 2026. The exact date, vote breakdown, and written reasoning of the Supreme Court's decision were not detailed across the available reports. As a result of the rulings, the proposed Postal Service mail ballot restrictions remained blocked, allowing existing mail voting procedures to continue as states began distributing ballots for the midterms. It remains unresolved how the D.C. federal judge's freeze and Judge Talwani's Boston case specifically related to or fed into the Supreme Court's action, and whether further legal proceedings or appeals are expected. The precise scope of the original USPS rule and its intended implementation timeline were not fully specified in the reporting.
