On Saturday, as the military parade in D.C. takes place, the Chicago area is preparing for "No Kings Day" protests against the Trump administration.

Protesters are expected to gather in the Chicago area and the suburbs as part of a nationwide movement called "No Kings."

A man arrested for impersonating a police officer during an anti-ICE protest in Chicago had a loaded semi-automatic weapon, badges and fake documents, police sources said.

The Chicago Loop is expected to see its third large-scale protest this week against ICE raids and the Trump administration. It comes as ICE tactical teams are supposedly set to begin work in the city,

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

The woman was taken to Northwestern Memorial Hospital where she was treated and released, Chicago police said.
