Soldiers mobilized by President Trump protected ICE agents on their raids in Los Angeles. The state of California said the deployment was illegal.

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.

Military-style vehicles and National Guards troops have blocked a portion of 4th Street in front of the Ronald Reagan Federal Building and Courthouse.

National Guard troops began protecting immigration agents as they made arrests in Los Angeles on Tuesday, an expansion of their duties that had been limited to protecting federal property.

Protests in Los Angeles appeared to quiet overnight, but new ones are popping up in other cities. Trump has deployed more than 4,000 National Guard troops and 700 Marines to the protests.

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

Meanwhile, Governor Gavin Newsom asked a court to put an emergency stop to the military helping federal immigration agents, with some guardsmen now standing in protection around agents as they carried out arrests.

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.
