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.

President Donald Trump has built his presidency around stretching the bounds of presidential authority, and his response to protests over an immigration crackdown in Los Angeles is no exception.

Defense Secretary Pete Hegseth on Tuesday defended the administration's mobilization of the National Guard and members of the Marine Corps to Los Angeles amid ongoing immigration protests.

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

National Guard troops with riot shields pushed protesters into the streets, as tear gas was deployed and less-than-lethal rounds exploded in the roadway.

President Donald Trump is moving swiftly to act on his immigration promises with little internal restraint, determined to test the bounds of his executive authority in order to fulfill the promises of his reelection campaign.

National Guard troops arrived in downtown Los Angeles on Sunday after being ordered into the city by President Trump in response to a weekend of violent clashes between law enforcement officers and protesters triggered by immigration enforcement operations in the area on Friday.
