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.

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 deployed 4,000 National Guardsmen and 700 Marines to LA. But California Gov. Gavin Newsom and California Attorney General Rob Bonta are suing the Trump administration, saying they unlawfully "trampled over" California’s sovereignty when they federalized the California National Guard.

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

California on Tuesday asked a federal court for a temporary restraining order blocking the Trump administration's deployment of National Guard forces and U.S. Marines to Los Angeles.

Homeland Security Secretary Noem blamed California Gov. Newsom for the need to deploy the National Guard to Los Angeles protests.

Trump border czar Tom Homan announces National Guard deployment to Los Angeles County after anti-ICE demonstrations turned violent, stating authorities won't apologize for enforcing the law.

A Department of Homeland Security request for 21,000 National Guard troops to support "expansive interior immigration enforcement operations" includes a call for troops to search for unaccompanied children in some cases.
