A federal judge in Missouri on Tuesday temporarily stopped the state from using its old congressional districts in the November election.

This decision came just after the U.S. Supreme Court refused to hear an appeal from Missouri’s Republican attorney general.

The legal fight started when Missouri’s top court ruled that new districts supported by President Donald Trump could not be used.

That court said the new map was automatically paused because citizens had turned in petition signatures.

Those signatures asked for a statewide vote on the map.

The U.S. Supreme Court allowed that ruling to stand.

The new districts were used in the August primary, and the winners were already confirmed.

U.S. District Judge Stephen Clark then issued a temporary order.

This order stops Missouri from using anything other than the new Republican-backed districts.

The question of which map will apply in November is still not settled.

The new map targeted the 5th Congressional District, held by Democratic Rep. Emanuel Cleaver.

It moved parts of Kansas City into nearby Republican districts.

It also stretched Cleaver’s district into rural areas.

Missouri’s Republican secretary of state had rejected the petition, but the state Supreme Court changed that decision.

The vote on the map will now appear on the November ballot as Proposition A.
