On October 23, 2025, U.S. Border Patrol Commander Gregory Bovino deployed tear gas and pepper spray against protesters in Chicago's Little Village neighborhood in response to immigration enforcement operations. Video evidence documented Bovino throwing a tear gas canister into the crowd, allegedly in violation of a federal court order prohibiting such tactics without imminent threat. The Department of Homeland Security claimed Bovino was struck by a rock, but witnesses and video evidence contradicted this account. On October 24, Federal Judge Sara Ellis ordered Bovino to appear in person to answer allegations that he violated the temporary restraining order.
