California will face off with Washington in court on Thursday over President Donald Trump's deployment of U.S. troops in Los Angeles after demonstrators again took to the streets in major cities to protest Trump's immigration crackdown.

Police and elected officials say the troops and Marines sent by the Trump administration are not properly trained to interact with civilians. A judge will decide whether to limit their duties.

The protests taking place across Los Angeles are heightening fears in America's largest county, a place still recovering from the wildfires tragedy.
