What to know about Trump’s deployment of National Guard troops to LA immigration protests

LOS ANGELES (AP) — Marines and additional National Guard troops were headed to Los Angeles on President Donald Trump’s orders in response to protests over immigration raids.

The authorization came amid mostly peaceful protests in the city on Monday.

California officials sued Trump on Monday to roll back the administration’s National Guard deployment, saying the president trampled over the state’s sovereignty. Local officials and Gov. Gavin Newsom don’t want the military presence and the police chief has said it creates logistical challenges for safely handling protests.

The 2,000 Guard members authorized Monday are an addition to the 2,100 Guard troops the president previously mobilized for the protests Sunday morning. Trump also deployed 700 Marines to help them Monday.

Trump, a Republican, said in a post on his social media site that the city would have been “completely obliterated” if he had not sent Guard members.

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