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.

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.

Twenty-seven arrests were made at immigration protests in downtown L.A. on Sunday on suspicion of throwing a Molotov cocktail at an officer and driving a motorcycle into a line of police, authorities said.

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 public fight between California Gov. Gavin Newsom and President Donald Trump keeps intensifying, with name calling, insults and accusations traded over television and social media networks.

Dozens of mayors from across the Los Angeles region banded together to demand that the Trump administration stop the stepped-up immigration raids that have spread fear across their cities and sparked protests across the U.

The downtown curfew encircles the downtown civic center, including City Hall, the main county criminal courthouse, LAPD headquarters and federal buildings.

The curfew went into effect in part of downtown Los Angeles amid ongoing protests over the Trump administration’s immigration crackdown.
