DOWNTOWN — Grant Park’s Butler Field was an ocean of homemade signs, banners and costumes Saturday as thousands of Chicagoans descended on Downtown streets for the third iteration of the nationwide “No Kings” protests.

The rallies and marches, organized by progressive group Indivisible and a coalition of hundreds of organizations across the U.S., have drawn some of the largest protest crowds in American history. Millions demonstrated against President Donald Trump’s administration during the previous two protests — with over 250,000 attendees reported at the “No Kings” march and rally in Chicago in the fall, according to Indivisible Chicago.

Saturday’s rally and march had an estimated attendance of 200,000, filling a mile of Loop streets end-to-end, according to an Indivisible spokesperson. It appeared less well-attended than the rally on Oct. 18, when the high temperature at Northerly Island hit 72 degrees in the afternoon. On Saturday, the temperature at the lakefront weather station hit only 44 degrees.
