The Supreme Court ruled 5-4 that states can count mail-in ballots that arrive after Election Day as long as they were postmarked by Election Day, rejecting a legal challenge brought by the Republican National Committee. This decision protects election laws in more than half the states and D.C. that have mail-ballot grace periods. President Trump criticized the ruling and called for Congress to pass the SAVE Act to tighten voting requirements, but the Court's decision affirms that states retain significant authority over their own election administration rules.
