Federal Judge Charles Breyer blocked the Trump administration's deployment of California National Guard troops in Los Angeles, ordering their control returned to Gavin Newsom.Breyer criticized the federalization for immigration operations, stating it risked creating a "national police force" without sufficient justification, noting some of the 300 Guardsmen had been sent to other states.The temporary injunction halts a deployment that began in June, with the Trump administration having until Monday to appeal the decision, despite a previous Ninth Circuit ruling upholding federal authority.
