A federal judge in Chicago dismissed a lawsuit filed by the U.S. Justice Department challenging the sanctuary policies of Illinois and the city of Chicago. The lawsuit, brought during Donald Trump's second term as president, accused the state and city of unlawfully interfering with federal immigration enforcement efforts. The judge, Lindsay Jenkins, a Biden appointee, ruled that the federal government lacks constitutional authority to compel states and municipalities to cooperate with immigration enforcement. This ruling upholds the sanctuary policies that limit local officials' cooperation with federal immigration authorities.
