People gathered in Chicago and the suburbs Saturday for a "No Kings" protest amid ongoing federal immigration enforcement operations in the area.

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.

The No Kings rally in Downtown Chicago was just one of many planned for around the Chicago area and the country.

The gatherings are part of a mass mobilization across the U.S. and globe positioned as a denouncement of President Donald Trump and his administration’s policies. In Chicago, they come amid sustained immigration raids.

Speaking at a "No Kings" rally in Washington, D.C., Bill Nye, the former host of "Bill Nye the Science Guy," urged lawmakers to “stop the abuses of this petulant president [Trump] and his circle of sycophants,” declaring, “No thrones, no crowns, no kings."

People turned out in large numbers across the Chicago area and the nation at "No Kings" events Saturday to oppose the Trump administration.

Activists held “no Kings” protests in New York, DC, and cities around the country to blast President Trump and accuse him of executing an illegal power grab. The vibe was festive at many protests

Illinois Gov. JB Pritzker struck a defiant tone as he addressed protesters in Chicago, where high-profile clashes between residents and federal immigration authorities have taken place in recent weeks.
