The Chicago Police Department has canceled officers' days off for the weekend in preparation for "No Kings Day" mass protests and other planned events in the city, but CPD said it's ready to act quickly.

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.

A car sped through a protest in Chicago today that drew thousands to the Loop to decry Trump policies and ICE.

A vehicle was seen speeding through the crowd and several protesters were detained during the Tuesday demonstration that drew thousands to downtown Chicago, voicing opposition to the Trump administration's stepped-up use of force against immigrants.

The city is bracing for more demonstrations in the coming days as more U.S. Immigration and Customs Enforcement raids are expected in Chicago too.
