Arrests were almost exclusively for charges of failure to obey a lawful order, Denver police said, but some included interference with police authority, unlawful throwing of projectiles, and obstruction of streets.

Three dozen protesters were arrested Saturday night in Denver on investigation of charges ranging from blocking streets to resisting arrest, according to the police department.

Millions of people turned out for "No Kings" protests nationwide on Saturday that were largely peaceful though there were some arrests and police had to disperse unruly crowds, including in Georgia and Los Angeles.
