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.

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.

A huge and peaceful crowed turned out for the "No Kings" rally, shutting down much of the Loop as part of a nationwide protest movement to denounce the Trump administration.

Tens of thousands of Americans joined "No Kings" protests across the United States against the Trump administration.

The Houston demonstration is one of several planned in the region throughout the day and is expected to draw thousands of protesters.

Chicago is an anchor city for the "No Kings" protests Saturday, and city officials said they are prepared for the crowds expected.
