California sues over National Guard deployment to L.A. for protests, immigration raids in 2020.

California argues that the Trump administration violated the Posse Comitatus Act by deploying National Guard troops to Los Angeles in 2020 to suppress protests and support immigration raids. The state's attorney general claims the military's involvement in civilian law enforcement is illegal. U.S. District Judge Charles Breyer will decide if the government acted unlawfully. The trial also examines the federal government's authority to deploy troops in such situations.
