On October 25, 2025, Border Patrol agents used tear gas in Old Irving Park, a Chicago neighborhood, just minutes before the scheduled annual Halloween parade, resulting in its cancellation.
The incident occurred despite a request from Democratic Illinois Gov. JB Pritzker to pause ICE raids for Halloween, which was denied by DHS head Kristi Noem.
Some claims stated that ICE "tear gassed children," however, it was unclear how close any children were to the tear gas deployment.
The incident led to the spread of a rumor online that a Halloween parade had been disrupted by U.S. immigration agents.
