On October 25, 2025, federal immigration agents from Border Patrol used tear gas in Old Irving Park, a Chicago neighborhood, just minutes before the annual Halloween parade was set to begin, resulting in its cancellation.
The incident occurred on the same day as the scheduled parade, with numerous local reports and witness testimony in court documents confirming the events. The agents were from Border Patrol under Customs and Border Protection, a separate agency from ICE, both of which are immigration enforcement agencies under the Department of Homeland Security.
Some claims stated that ICE "tear gassed children," however, it was unclear how close any children were to the tear gas deployment.
Following the incident, DHS head Kristi Noem denied a request from Democratic Illinois Gov. JB Pritzker to pause ICE raids for Halloween.
