A crowd-size expert from the U.K. estimates that between 10,000 to 15,000 people attended Saturday's protest in downtown Chicago. But some estimates say 75,000 people gathered downtown.

An estimated 75,000 people flooded the Loop for the local edition of the nationwide movement to protest President Donald Trump.

The largely peaceful protests during the "No Kings Day" demonstration in downtown Los Angeles took an intense turn in the afternoon. Police ordered the crowd to disperse at about 4:15 p.m. PDT near Alameda Street and Temple Avenue, according to the Los Angeles Police Department's Central Division.

Thousands gathered in Daley Plaza and in suburban events in protests timed to coincide with a military parade in Washington celebrating the Army's 250th anniversary and President Donald Trump's 79th birthday.
