The move appeared to be the first time in decades that a state’s national guard was activated without a request from its governor.

By Jorge Garcia and Arafat Barbakh LOS ANGELES (Reuters) -California National Guard troops clashed with protesters in Los Angeles on Sunday hours after arriving in the city on the orders of President Donald Trump to quell demonstrations against immigration raids carried out as part of Trump's enforcement measures.

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.
