Millions of people across the country are expected to join in protest this weekend against Donald Trump’s administration, a movement intended to coincide with the president’s planned military parade in Washington — and the commander-in-chief’s 79th birthday.

The No Kings events come after days of protests following raids by U.S. Immigration and Customs Enforcement in Los Angeles, and Trump’s subsequent deployment of thousands of National Guard and U.S. Marines troops to “temporarily protect” ICE and other federal personnel, along with federal property.

Cities large and small across the U.S. saw crowds gather Saturday for planned "No Kings" protests against President Trump.

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.

A breakdown of who was charged with what and why wasn't immediately available, but the protest and related marches shut down streets throughout the day and into Saturday night.

Saturday's No Kings protest at the Monroe County Courthouse square was peaceful except for 1 man taken away by police.
