The Supreme Court on Tuesday rebuffed an appeal from Missouri officials who wanted to use new congressional districts backed by President Donald Trump in the November election, a defeat for Republicans who had hoped the new map could help them hold onto their slim House majority. The justices let stand a decision by Missouri's top court, which said the new districts were automatically suspended by a citizen petition demanding a statewide vote. The ruling marks a rare setback for Republicans in a nationwide redistricting battle that Trump urged Republicans to launch last year.
