The Supreme Court has ruled that California may use its newly drawn congressional voting maps this November, rejecting a request from California Republicans to block them. State Republicans, backed by the Trump administration, argued that the map-makers used race illegally when setting district boundaries. However, a lower court disagreed with that claim. Voters originally passed the redistricting plan, known as Proposition 50, last November. This ruling follows a similar case where the Supreme Court allowed Texas to use its own redrawn map in 2026, a move that prompted California's current legal strategy.
