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.

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

So-called "No Kings" protests took place in Chicago and across the U.S. on Saturday. The protesters gathered to reject "authoritarianism," according to organizers. The No Kings Day of Defiance is expected to be the largest single-day mobilization since President Trump returned to office.
