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

The restraining order request is focused on a growing expectation among California officials that troops will soon be sent on arrest missions.

Armed National Guard troops are accompanying immigration agents as they carry out mass deportation raids on the streets of Los Angeles, multiple sources told The Post.

State AG Rob Bonta called the federal government's order "unlawful" and "unprecedented" as anti-ICE raid demonstrations emerged in Los Angeles.

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.

Windows were smashed and merchandise was stolen at LA’s Broadway Apple store Monday night, while down the block the Adidas store was broken into and robbed of sneakers by frenzied crowds.

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.

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.”
