Supreme Court again blocks Missouri from using Trump-backed congressional maps

The Supreme Court turned back another effort to use Missouri congressional maps supported by President Donald Trump.

"The application for stay presented to Justice [Brett] Kavanaugh and by him referred to the Court is granted," Thursday's ruling read.

The court's brief order was unsigned and gave no explanation, as is common when the justices handle emergency matters. No justice publicly dissented from the decision.

"After repeated legal victories defending Missouri's fair and lawful map, this 11th-hour ruling pulls the rug out from under voters who already cast their primary ballots," RNC Election Integrity Communications Director Ally Triolo wrote in a statement. "Changing the rules mid-election is reckless and wrong."

The court's decision came after U.S. District Judge Stephen Clark ordered Missouri to use the new map, conflicting with a unanimous ruling by the Missouri Supreme Court that said the districts had not legally taken effect and that the state's older map should be used unless voters approve the changes.

Following the U.S. Supreme Court's stay, Missouri Secretary of State Denny Hoskins said his office is directing local election authorities to use the 2022 congressional map.

"Following the United States Supreme Court's stay, the only governing court order in effect is from the Missouri Supreme Court. In accordance with that order, my Office is directing local election authorities to use the 2022 congressional map," Hoskins said in a statement.

Republican state officials have argued it would violate voters' federal rights to switch districts before the general election.

Republicans currently hold a 219-214 majority in the House, including one independent who caucuses with the GOP.
