National Security Leaders for America Files Amicus Brief in Ninth Circuit Opposing Federalization of California National Guard

NSL4A announced today that it has filed an amicus curiae brief in the U.S. Court of Appeals for the Ninth Circuit in support of California Governor Gavin Newsom’s challenge to the federalization of the California National Guard. 

The brief, filed by NSL4A’s counsel at Bryan Cave Leighton Paisner LLP, underscores the historic and legal limits on the President’s authority to seize control of state National Guard units without a governor’s consent. At issue is the President’s June 7, 2025, order to federalize and deploy 4,000 California Guard members to Los Angeles under 10 U.S.C. § 12406, despite Governor Newsom’s determination that local police forces were sufficient to maintain order.
