Protests over President Trump's immigration enforcement raids and his mobilization of the Marines and National Guard in Los Angeles have spread to other major U.S. cities.

During a protest later that day outside of the Metropolitan Detention Center in downtown Los Angeles, the union says Huerta was serving as a community observer and documenting ICE activities when he was arrested by federal agents for allegedly interfering and blocking a law enforcement vehicle.

California Gov. Gavin Newsom called the move "purposefully inflammatory" and one that "will only escalate tensions."
