Federal immigration enforcement actions in Chicago have ignited a significant controversy following the use of tear gas by agents in residential neighborhoods, including near an elementary school. The incidents, part of a DHS initiative dubbed "Operation Midway Blitz," have prompted community backlash and an official defense from federal authorities.
In one widely reported event in early October 2025, U.S. Border Patrol agents deployed tear gas on a street in a North Side neighborhood during an immigration sweep. Witnesses and local reports indicated the chemical agent was used just outside a children's play cafe and an elementary school, causing parents and teachers to rush children to safety. Community members and local officials have expressed outrage, describing the tactics as excessive and traumatizing for the children who were exposed to the chaos.
The Department of Homeland Security (DHS) has defended the agents' conduct, describing the deployment of chemical irritants as necessary "crowd control measures." In a statement, the agency asserted that its personnel were met with hostility and that the measures were taken to ensure their safety. A senior official later testified that agents assigned to immigration enforcement in the city are equipped with body cameras, and defended the use of tear gas as a legitimate response to perceived threats during the operations.
The use of such tactics is under intense scrutiny, particularly given a prior federal court order that restricts federal agents from using tear gas and other aggressive riot control weapons unless they face life-or-death circumstances. The rules of engagement for federal agents are now a central focus of the debate. The controversy has escalated tensions between federal authorities and Chicago city officials, who have criticized the operations for spreading fear. The ongoing fallout includes scheduled testimony from U.S. Border Patrol Chief Jason Bovino, who is expected to face questions from lawmakers about his agents' actions in the city.
