Chicago police officers pin a demonstrator to the ground and arrest them at West Washington Street and North State Street during a protest in the Loop, decrying increased immigration enforcement across the country, Tuesday, June 10, 2025.

According to the Chicago Police Department, one person was taken into custody after striking an officer during the “No Kings” march and rally on Saturday.

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.

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.

Tuesday’s at times contentious protest downtown marks the latest flashpoint in the volatile nationwide struggle over President Trump’s push to carry out mass deportations.
