The U.S. Supreme Court on Monday upheld state laws permitting counting of mail‑in ballots received after Election Day, rejecting a Republican challenge to Mississippi's five‑day grace period. The justices reversed a lower court ruling in a 5‑4 decision; the lower court had found Mississippi's law inconsistent with federal timing rules for presidential, Senate and House elections. The decision was described as a judicial setback for President Trump, who last year said he would try to stop nationwide use of mail‑in ballots ahead of November's congressional elections.
