(Chicago, IL) — Chicago is about to become the first city in the country to sue over President Trump’s immigration rules. Mayor Rahm Emanuel yesterday said his lawyers will file a lawsuit today that challenges the president’s proposal to only send federal money to cities that follow federal immigration laws. It’s part of the president’s crack down on sanctuary cities. Emanuel says he doesn’t want to see Chicago police officers used as pawns and says he won’t sit by and allow “our residents have their fundamental rights isolated and violated.”
