President Trump ordered National Guard troops to the area after clashes over immigration-enforcement operations.

The National Guard has at times detained protesters in its deployment to Los Angeles, an official said Wednesday, as demonstrations against Immigration and Customs enforcement raids spread to other major cities.

A relative state of calm in Los Angeles began to crumble early Sunday afternoon as demonstrators confronted federal authorities guarding a downtown detention facility where chaos erupted as National Guard soldiers deployed tear gas on an increasingly agitated crowd.
