One hundred thousand people flooded Chicago's Grant Park on Saturday for the "No Kings" protest against President Trump — with many rallying against the Department of Homeland Security's aggressive immigration crackdown.

Chicago was one of dozens of cities nationwide that held "No Kings" protests Saturday. A quarter of a million people marched through downtown, organizers said.

Thousands of demonstrators across the country took to the streets for “No Kings Day,” a nationwide series of protests against the Trump administration, Saturday. Protesters began to pack into Grant Park at around noon.

The first "No Kings" Chicago protest was held in June in Daley Plaza and drew tens of thousands of demonstrators. Saturday's protest has been moved to Grant Park, a larger area that can accommodate more people.

District Judge Sara L. Ellis ordered ICE agents to wear body cameras after agents were seen deploying chemical weapons on protesters.

The DHS is facing questions over differing accounts of the shooting of a U.S. citizen in Chicago, as protests continue.

Several hundred volunteers are patrolling the streets of Chicago and its suburbs warning migrants of ICE's presence. This is part of a growing resistance to ICE's operations in Illinois.

Large crowds of protesters marched and rallied in cities across the U.S. Saturday for “ No Kings ” demonstrations decrying what participants see as the government’s swift drift into authoritarianism under President Donald Trump.
