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.

Chicago police spotted the suburban man leaving a parking garage Thursday evening in the 200 block of South Michigan Avenue, they said.

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.

Similar protests are set to kick off in more than 1,000 cities across the country on Saturday. The rallies are intended to counter the military parade President Donald Trump has planned to mark the U.

Jermont Terry reports on the protest that began in Federal Plaza and ended up circling the Loop and the Near North Side for hours, and Charlie De Mar reports on one incident early during the protest march where a car sped through the crowd.

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