The military has activated about 700 active-duty Marines who could be sent to Los Angeles, joining National Guard troops who were sent to the city to respond to protests, U.S. Northern Command said in a statement.

This appears to be the first time in decades that a state’s National Guard was activated without a request from its governor.

California leaders accused Trump of fanning protesters' anger, leading crowds to block off a major freeway and set self-driving cars on fire.
