People rally outside the U.S. Supreme Court following arguments heard in Louisiana v. Callais on March 24, 2025. On April 29, 2026, the nation's highest court struck down a Louisiana congressional map that a group of voters who describe themselves as “non-African American” had challenged as the product of unconstitutional racial gerrymandering. By a vote of 6-3, the justices left in place a ruling by a federal court that barred the state from using the map, which had created a second majority-Black district, in future elections.
