National Guard troops and protesters faced off in Los Angeles on Sunday in an uneasy impasse at a federal detention center in Los Angeles, before city police moved in to try to disperse the crowd.The tense gatherings followed two days of skirmishes over federal immigration operations that President Trump cited in his decision to send in the state’s National Guard over the governor’s objections.

The confrontation broke out Sunday in front of the Metropolitan Detention Center in downtown Los Angeles as a group of demonstrators shouted insults at members of the Guard lined shoulder to shoulder behind plastic riot shields.

President Trump bypassed the authority of Gov. Gavin Newsom to call up 2,000 National Guard troops to quell immigration protests.
