A federal judge in Chicago has dismissed a lawsuit filed by the U.S. Justice Department accusing Illinois and Chicago of obstructing President Donald Trump’s efforts to enforce federal immigration laws. The ruling marks a significant setback for Trump’s campaign to challenge “sanctuary” policies across the U.S.
U.S. District Judge Lindsay C. Jenkins, appointed by President Joe Biden, ruled that Illinois’ TRUST Act and Chicago’s 2012 ordinance—which restrict cooperation with federal immigration enforcement—do not violate the U.S. Constitution’s Supremacy Clause. Instead, Jenkins cited the Tenth Amendment, which reserves powers not delegated to the federal government for the states, protecting local autonomy in immigration-related enforcement decisions.
Trump, who has vowed to deport millions of undocumented immigrants, has repeatedly clashed with Democratic-led cities like Chicago over sanctuary policies. Supporters of these laws argue that cooperating with federal immigration enforcement discourages undocumented residents from reporting crimes or cooperating with police, undermining public safety. Critics, including Trump and his allies, claim such policies shield individuals in the country illegally from accountability.
The Justice Department filed the lawsuit in February, alleging the state and city laws conflicted with federal immigration authority. Similar lawsuits are ongoing against New York City and Los Angeles as Trump intensifies his crackdown on local sanctuary policies while campaigning for broader deportations.
The dismissal is a legal victory for Illinois and Chicago, reinforcing their right to limit participation in federal civil immigration enforcement. The ruling could also influence pending cases in other sanctuary jurisdictions. The Justice Department and White House have not yet commented on the decision.
This decision underscores the ongoing legal battles over immigration enforcement powers between federal and local governments amid heightened national debate on immigration policy.
