(FOX NEWS) – The Supreme Court’s conservative majority on Monday appeared poised to overturn state laws from Mississippi and other U.S. states that allow for the counting of mail-in ballots received after Election Day — a major case that could upend voting laws for millions of Americans just months before the 2026 midterm elections.

At issue is a Mississippi voting law that allows the state to count mail-in ballots that are received up to five days after the election, so long as they are postmarked by or before Election Day.

President Donald Trump has focused on mail-in voting during his second White House term, and has argued that such laws undermine voter confidence. Similar laws are currently on the books for at least 13 states and the District of Columbia, in a sign of the wide-ranging nature of the case.

During roughly two hours of oral arguments Monday, conservative justices appeared sympathetic to the argument made by the Trump administration’s lawyer, U.S. Solicitor General D. John Sauer, who noted that the Mississippi law and similar voting laws in other states could erode voter trust in election results.
