Tennessee’s Republican-dominated state Legislature on Thursday approved a new congressional map that breaks up a decades-old district in the majority-Black city of Memphis into three Republican-leaning districts. Governor Bill Lee promptly signed the legislation into law. Republicans believe the new map will help their party sweep all nine of Tennessee’s House seats. The legislation passed after Democratic lawmakers linked arms and walked out of the Tennessee House chamber, as protesters shouted slogans including “No Jim Crow!” and “Black votes matter!” Three protesters were arrested, including KeShaun Pearson, the brother of state Representative Justin J. Pearson. This follows last week’s Supreme Court ruling gutting Voting Rights Act protections for majority-Black districts.
