A federal appellate court is currently reviewing a challenge to Mississippi's mail-in ballot law, which permits the counting of ballots received up to five days after Election Day, provided they are postmarked by Election Day. The case, which has significant implications for election laws across multiple states, is being heard by a panel of three Trump-appointed judges on Tuesday. The law is being contested by GOP representatives who argue that it invites fraud and undermines voter confidence. The outcome of this case, just weeks before Election Day, could potentially reach the US Supreme Court and impact similar laws in other states.
