Los Angeles police have swiftly enforced a downtown curfew, making arrests moments after it took effect, deploying officers on horseback and using crowd control projectiles to break up a group of hundreds demonstrating against President Donald Trump’s immigration crackdown.

4:56 p.m. EDT U.S. District Judge Charles Breyer turned down Newsom’s request for an emergency ruling that would have blocked federal troop deployment in Los Angeles, giving Trump until Wednesday at 2 p.m. EDT to file a response to Newsom’s lawsuit (Newsom can file his response to Trump by Thursday at 12 p.m. EDT).

The president defends his decision on using the military in the city before an audience at Fort Bragg. California officials blame the administration for inflaming tensions.

California sued Trump over the deployment, with the state attorney general arguing that the president had “trampled” the state’s sovereignty. California leaders accused Trump of fanning protesters’ anger, leading crowds to block off a major freeway and set self-driving cars on fire.
