The California Republican Party has petitioned the U.S. Supreme Court to block California from implementing the redrawn congressional maps approved by voters in November 2025, a lawyer for the state party confirmed on Jan. 20.
“Today, we filed an Emergency Application with the U.S. Supreme Court challenging California’s new congressional map enacted through Proposition 50,” Mark Meuser, a Dhillon Law Group attorney who represents the California Republican Party, wrote in a post on X.
