California Gov. Gavin Newsom (D) has argued that the deployment is “an illegal act, an immoral act, an unconstitutional act.”

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.

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.

California said the Trump administration’s deployment of the National Guard and US Marines to respond to protests in Los Angeles was illegal and cannot continue “unchecked.”
