Minnesota and Illinois have launched major legal challenges against federal immigration enforcement, invoking the 10th Amendment in an effort to block or limit Immigration and Customs Enforcement operations within their borders. State officials argue that the surge of ICE and Border Patrol agents represents federal overreach that interferes with state sovereignty, public safety, and local governance. The lawsuits claim aggressive enforcement actions have disrupted schools, businesses, tourism, and essential public services, while spreading fear across immigrant communities.
