Missouri Supreme Court blocks Trump-backed congressional map, orders statewide referendum

The Missouri Supreme Court unanimously blocked the new congressional map backed by Donald Trump from being used in the November election, and ordered a statewide referendum on its fate. The old 2020 census-based map remains in effect for the 2026 general election. The ruling followed a petition process to vote on the map and could still be appealed to the U.S. Supreme Court, illustrating a rare Republican setback in mid-decade redistricting amid broader national fights.
