The National Guard has been deployed to Los Angeles in the past in response to civil disorder and natural disasters.

The National Guard members were met by a crowd of protesters marching to the Metropolitan Detention Center in downtown L.A. Reports said the crowd disappeared after authorities deployed tear gas, but they reassembled,

Demonstrators gathered in a tense city following two days of skirmishes between protesters and federal officers over immigration operations that prompted the White House’s rare move to deploy troops without first being asked by the state.
