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

Unlike the 1992 riots, protests have mainly been peaceful and been confined to a roughly five-block stretch of downtown LA, a tiny patch in the sprawling city of nearly 4 million people. No one has died. There’s been vandalism and some cars set on fire but no homes or buildings have burned.

The California Governor has sued the U.S. President over the mobilization of the National Guard, calling it “an unmistakable step toward authoritarianism.”

President Donald Trump has sent U.S. Marines to Los Angeles in an effort to quash anti-ICE protests that have ravaged parts of the city on Tuesday. Images from L.A. show masked protesters blocking roads,

The demonstrations featured more violence and arrests, with some protesters throwing objects at law enforcement, and authorities responding with less-lethal munitions.

4:47 p.m. EDT The Trump administration asked the judge to reject Newsom’s request and allow it to respond by Wednesday, calling Newsom’s attempt to block the deployment of federal troops “legally meritless” and saying it would jeopardize the safety of Homeland Security personnel and interfere with the government’s ability to carry out operations.

Monday's protests were largely calmer than Sunday's clashes. California officials insist that the 4,000 National Guards troops and 700 active duty Marines en route to L.A. are an unnecessary abuse of power by Trump.
