National Guard troops arrived in downtown Los Angeles on Sunday after being ordered into the city by President Trump in response to a weekend of violent clashes between law enforcement officers and protesters triggered by immigration enforcement operations in the area on Friday.

Tensions between the Trump administration and California intensified this weekend as President Donald Trump decided to deploy 2,000 National Guard members to the Los Angeles area, a move the state’s Democratic leaders cast as an unnecessary escalation amid protests over the administration’s immigration policies.
