US Supreme Court rejects Missouri's Trump-backed congressional map

The US Supreme Court has declined to intervene in a Missouri redistricting dispute, effectively blocking the use of a new congressional map endorsed by President Donald Trump in the upcoming November elections. The decision, announced on Tuesday, is a setback for Republican officials who had hoped the revised districts would bolster their chances of retaining a narrow majority in the House of Representatives.

The justices allowed a ruling by Missouri's highest court to stand. That state court had determined that the new district boundaries were automatically suspended because a citizen-led petition had triggered a statewide referendum on the map. The legal challenge arose after Missouri officials sought to implement the new districts despite the pending public vote.

The outcome marks a rare defeat for Republicans in the ongoing national redistricting battle, a process that President Trump had urged his party to aggressively pursue last year. With the Supreme Court declining to hear the appeal, the existing congressional map will remain in effect for the November election, while the fate of the proposed districts will be decided by Missouri voters.
