The state and cities filed a lawsuit in federal court on Monday, along with a request for a temporary restraining order to halt the enforcement action or limit the operation.
The Department of Homeland Security says it's surging more than 2,000 immigration officers into Minnesota, and that it has made more than 2,000 arrests in the city since the push began last month. ICE has called the Minnesota surge its largest enforcement operation ever.
The lawsuit alleges that the operation violates federal law because it's arbitrary and capricious, since it says other states aren't seeing commensurate crackdowns. And while the Trump administration says it's about fighting fraud, the lawsuit says ICE agents have no expertise in combating fraud in government programs.
