An armed man was arrested on Saturday in the area of a "No Kings" rally in West Chester, Pennsylvania, police said.

The American Civil Liberties Union said over 5 million people participated in protests against the Trump administration on June 14.

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.

LAPD said law enforcement arrested 38 people following the "No Kings" protests in downtown Saturday afternoon.

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.

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.

At least one person was critically injured Saturday in a shooting at a protest against President Donald Trump in Salt Lake City. It came hours after two Democratic lawmakers in Minnesota were shot dead by a gunman.

Up to 300 gathered along State Road 100 and Belle Terre Parkway in Palm Coast. Another protest was held near Old Kings Road.
