President Donald Trump ordered the deployment of 2,000 National Guards troops to quell immigration protests in Los Angeles, overriding California Gov. Gavin Newsom’s objections in a rare move.

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.
