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.

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.

Trump sent National Guard troops to California amid days of protesting federal immigration raids. Here's what's usual, and unusual, about the order.

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

California Attorney General Rob Bonta said Monday that he’ll soon file a lawsuit against the Trump administration for federalizing National Guard troops this weekend.

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.

HOW WE GOT HERE: The protests erupted after Immigration Customs Enforcement (ICE) officers on Friday carried out raids in three locations across L.A., where dozens of people were taken into custody. Newsom called the raids “chaotic federal sweeps” that aimed to fill an “arbitrary arrest quota.”
