On October 25, 2025, federal immigration agents from Border Patrol released tear gas in Old Irving Park, a Chicago neighborhood, just before the annual Halloween parade was set to begin.
The incident resulted in the parade's cancellation, according to numerous local reports and witness testimony in court documents.
DHS head Kristi Noem denied a request from Democratic Illinois Gov. JB Pritzker to pause ICE raids for Halloween, following the incident.
Some claims stated that ICE "tear gassed children," however, it was unclear how close any children were to the tear gas deployment.
Border Patrol, under Customs and Border Protection, is a separate agency from ICE, but both are immigration enforcement agencies under the Department of Homeland Security.
