Tennessee Republicans passed a new congressional map on Thursday that eliminates the state's only majority-Black House district, and the NAACP immediately filed an emergency lawsuit in state court to block it. The move is remarkable because Tennessee law explicitly banned congressional redistricting between census cycles for over 50 years — this is the first time the state has done it. The lawsuit argues the map violates Tennessee's state constitution and statutory law, and comes days after a Supreme Court decision weakening the Voting Rights Act emboldened Southern states to push through similar changes.
