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.

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

Part of a network of nationwide protest, the "No Kings" protest in Memphis drew thousands of peaceful protesters from around the area.

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.

The "No Kings" protests were scheduled in Connecticut as early as 9:30 a.m. in Canton and Glastonbury and could last elsewhere until 6 p.m.

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.
