U.S. Immigration and Customs Enforcement conducted a large-scale enforcement operation across Wisconsin over the final weekend of June 2026, resulting in 39 arrests in one of the state's largest operations in recent years. The operation was notable for its public, daylight nature and included arrests in Milwaukee and surrounding areas. ICE agents arrested a Dominican woman in front of her 7-year-old daughter, Mexican twins in their driveway, and a Salvadoran man outside a courthouse following a traffic court appearance. ICE stated those arrested had criminal histories including sexual assault, DUIs, domestic abuse, and drug possession. However, an attorney representing arrestees stated none had prior convictions in Wisconsin or outstanding removal orders, and some detainees were asylum seekers with valid work permits. Immigrant advocates documented that ICE agents used city and county property as staging areas without permission, wore face masks in violation of a local ordinance, and used excessive force. Detainees were held in Wisconsin, Illinois, and as far as Florida.
