Summary
A U.S. federal judge ruled that the Trump administration’s deployment of the National Guard and Marines in Los Angeles during June 2025 protests violated federal law prohibiting military involvement in domestic law enforcement. The administration argued the deployment was to protect federal property, but the court concluded it was for law enforcement purposes, banning federal involvement in civilian arrests. California Governor Newsom sued, citing the illegality of unilateral military action. The ruling may restrict future administrations’ ability to deploy military forces domestically without state consent. Trump also announced National Guard deployments in Washington, D.C., and proposed similar actions in Chicago, raising further legal concerns. Experts suggest the ruling, if upheld in higher courts, could significantly limit federal authority in such cases.
