President Donald Trump said Thursday that he's backing off a planned surge of federal agents into San Francisco after speaking to the mayor, as protesters gathered outside a U.S. Coast Guard base where they were located. Trump had been threatening to send the National Guard to the city to to quell crime and U.S. Customs and Border Protection agents began arriving in the region early in the day for a possible ramp up of immigration enforcement. As protesters gathered outside the US Coast Guard base in Alameda County, California, on Thursday morning, one of them was hit with a device. #trump #California #SanFrancisco #ICE #BorderPatrol #Immigration
