Downtown Los Angeles was bustling with dog-walkers and commuters touting coffee cup after the first night of curfew meant to tamp down tensions following days of protests over President Donald Trump’s immigration crackdown.

The deployment of troops to Los Angeles raises questions about what Trump can and can't do with the military on U.S. soil, and whether he's crossing the line.

About 500 of the National Guard troops deployed to the Los Angeles protests have been trained to accompany agents on immigration operations, the commander in charge said Wednesday.

California Gov. Gavin Newsom said President Donald Trump is “pulling a military dragnet” across Los Angeles during a brief public address on Tuesday.

The curfew extends to sections of downtown Los Angeles where protests have turned into instances of vandalism and looting.

Trump deployed 4,000 National Guardsmen and 700 Marines to LA against the wishes of Newsom and Bass. Newsom sued the Trump administration, saying they unlawfully "trampled over" California’s sovereignty when they federalized the California National Guard.

After months of courting Republicans, the Democratic governor now warns Trump is undermining democracy with the military deployment in Los Angeles.
