Opponents of President Donald Trump’s administration are set to rally in nearly 2,000 cities and towns this weekend.

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.

In Los Angeles, 38 people were arrested downtown on Saturday night, police said Sunday. In Huntington Beach, police arrested a convicted felon they said had a loaded handgun.

Organizers of the “No Kings” demonstrations said millions had marched in hundreds of events. In Oregon, tens of thousands of people gathered in downtown Portland for two large protests -- one that began in Tom McCall Waterfront Park and the other at the Oregon Convention Center.

The county's sheriff had made incendiary remarks about police response should any violence occur. But nothing happened.

“ No Kings Day of Defiance” protests drew several thousand people around the Inland Empire throughout the day and into the night. At one point on Saturday evening, several hundred protesters present during the Riverside crash had merged with people who attended a large anti-ICE protest, which began earlier that day.

The sounds of one of Chicago’s largest protests in recent memory reverberated throughout downtown Saturday, as tens of thousands gathered in a united admonishment of President Trump.

Coordinated "No Kings" protests are happening from coast to coast, part of a "national day of peaceful protest" against the Trump administration, expected to draw millions. Protesters in some areas braved wet weather to raise signs and chant slogans supporting the rights of immigrants and criticizing what they see as Trump's power grab.
