Supreme Court Rejects Trump's Mail-In Ballots Rule Appeal

On June 29, 2026, the U.S. Supreme Court rejected an appeal from the Trump administration to lift a judicial block on a U.S. Postal Service rule impacting mail-in voting for the upcoming midterm elections. The Court indicated that the administration is unlikely to succeed in its challenge to the preliminary injunction from a U.S. District Court in Massachusetts. Justice Brett Kavanaugh noted that implementing the rule before the elections would violate the Administrative Procedure Act due to insufficient time for state and local election officials. This ruling may affect voter access and the political landscape, as Republicans currently have slim majorities in Congress.
