The Supreme Court on Monday also heard arguments in a key voting rights case in Louisiana which could have a major impact on the future of the already-weakened Voting Rights Act. The case centers on whether Louisiana’s new congressional map, which created a second majority-Black district, is unconstitutional. One-third of Louisiana’s population is Black. Last year, using the newly drawn maps, voters elected Cleo Fields, a Black Democrat, to represent the district, sending two Democrats from Louisiana to the U.S. House for the first time in a decade.
