The U.S. Supreme Court declined to allow Missouri congressional maps backed by President Trump to be used in the November midterm elections, leaving previous maps in effect.
Key facts
- The U.S. Supreme Court rejected a push to use Trump-backed Missouri congressional maps.
- The decision clears the way for older maps to be used.
- The dispute concerns the November midterm elections.
- The ruling was reported by CNBC on September 10, 2026.
The U.S. Supreme Court has again rejected an effort to use Missouri congressional maps backed by President Trump ahead of the November midterm elections, according to CNBC. The decision leaves older maps in place for the upcoming vote.
The court’s action means the Trump-backed maps will not be applied to the midterms, at least for now, according to CNBC’s reporting.
The dispute centers on which set of congressional district lines will govern how Missouri voters are represented in the November elections. Congressional maps determine the boundaries of the districts from which members of the U.S. House of Representatives are elected.
By declining to permit the newer, Trump-backed maps, the Supreme Court effectively clears the way for the previously established maps to be used, as reported by CNBC.
The outcome was described by CNBC as the latest instance of the court turning away a push to adopt the maps favored by the president ahead of the midterms.
Why it matters
Congressional maps shape which candidates and parties are favored in House races, so decisions about which maps apply can influence the balance of power in Congress. The Supreme Court's rejection means Missouri's midterm elections will proceed under existing district lines rather than the newer maps backed by President Trump.
