The Missouri Supreme Court on May 27 unanimously rejected a constitutional challenge to Missouri’s congressional redistricting plan that the state Legislature approved last year.

Missouri’s delegation to the U.S. House of Representatives currently has six Republicans and two Democrats. The new map, which supporters call the “Missouri First Map,” is expected to result in Republicans gaining one seat.
