Breyer, a Clinton appointee based in San Francisco, concluded that Trump's Los Angeles deploymentan operation overseen by Defense Secretary Pete Hegsethviolated a longstanding law meant to prevent domestic law enforcement by the military: the Posse Comitatus Act.

A federal judge ruled Tuesday that the Trump administration's deployment of U.S. military troops to Los Angeles during immigration raids earlier this year was illegal. U.S. District Judge Charles Breyer found the deployment violated the Posse Comitatus Act, which limited the use of the military for law enforcement purposes. He stayed his ruling to give the administration a chance to appeal. "President Trump and Secretary Hegseth have stated their intention to call National Guard troops into service in other cities across the country ... thus creating a national police force with the President as its chief," Breyer wrote.
