Seventeen people were arrested in connection with Saturday's "No Kings" protest in Denver -- one of over 2,000 affiliated protests across the country, in which organizers say over 5 million people attended to protest the Trump administration and its policies and actions.

More than a dozen rallies across the state were peace. Police used pepper balls and smoke on one group in Denver.
