Gov. Gavin Newsom says President Trump is "escalating the situation" by sending troops to L.A., adding fuel to the feud between the two

The Trump administration faces a legal challenge to its deployment of the military to protests. Tensions flared after President Trump sent troops, and protests spread to other U.S. cities.

President Trump has said the city would be burning without military intervention, but the protests have been confined to a relatively small area.

The National Guard has at times detained protesters in its deployment to Los Angeles, an official said Wednesday, as demonstrations against Immigration and Customs enforcement raids spread to other major cities.

The National Guard in Los Angeles has detained anti-ICE protesters while providing security for immigration operations, with officials expecting protests to escalate.

It was earlier this year that California Gov. Gavin Newsom was making nice with President Donald Trump as he sought help for his wildfire-battered state and moderating his approach ahead of a potential bid for the White House.

Thousands of people in cities across the U.S. have marched to protest President Trump's immigration crackdown. In Los Angeles, the city's police chief talked about the coordination with the National Guard and Marines.
