The Trump administration is facing new legal challenges as Democratic-led states move to block expanded federal immigration enforcement, setting the stage for another high-profile courtroom battle over states’ rights, public safety, and federal authority.
On Monday, Illinois Attorney General Kwame Raoul announced that Illinois and the city of Chicago have filed a lawsuit against the Trump administration, accusing federal immigration officers of using unconstitutional and aggressive tactics. Officials in Minnesota followed with a similar lawsuit later the same day.
Illinois Lawsuit Targets ICE and CBP Tactics
The Illinois complaint alleges that agents with U.S. Immigration and Customs Enforcement (ICE) and U.S. Customs and Border Protection (CBP) have conducted roving patrols, questioned residents without warrants, and, in some cases, detained U.S. citizens.
State officials claim these actions violate Fourth and Tenth Amendment protections and interfere with Illinois’ ability to manage public services, including education, healthcare, and local law enforcement.
Raoul said federal agents were operating in a manner that exceeded their authority, arguing that immigration enforcement during President Donald Trump’s second term has been more confrontational than in previous years.
The lawsuit, filed in federal court in Chicago, spans more than 100 pages and challenges DHS policies related to random questioning, warrantless arrests, and the use of crowd-control measures near schools, hospitals, and social-service centers.
DHS Responds: Sanctuary Policies to Blame
The Department of Homeland Security strongly rejected the allegations, calling the lawsuit politically motivated and legally unfounded.
DHS officials argue that sanctuary policies in Illinois and Chicago have allowed dangerous criminals to remain free, forcing federal authorities to step in. The department insists its agents are enforcing immigration law as required by Congress and the Constitution.
According to DHS, detentions involving U.S. citizens are rare and occur only during brief identity verification, after which individuals are released.
Minnesota Files Similar Lawsuit After ICE Surge
In Minnesota, Attorney General Keith Ellison accused the Trump administration of unfairly targeting the state following a surge of federal agents into Minneapolis and St. Paul.
The lawsuit comes after the fatal shooting of U.S. citizen Renee Nicole Good during an encounter involving an ICE agent, an incident that intensified protests across the Twin Cities.
Ellison claims the influx of roughly 2,000 federal officers disrupted schools, businesses, and local government operations. The Minnesota filing alleges that ICE and CBP now outnumber local police forces and are using unconstitutional enforcement methods similar to those cited in Illinois.
Political Leaders Clash Over Immigration Authority
Illinois Governor JB Pritzker and Chicago Mayor Brandon Johnson criticized the federal government’s actions, saying they undermine trust and public safety.
Meanwhile, DHS officials argue that cooperation from state and city leaders could have prevented the federal surge altogether. The department maintains that President Trump has a constitutional obligation to enforce immigration law, regardless of local political opposition.
What the Lawsuits Are Asking For
Both lawsuits ask federal judges to restrict ICE and CBP operations, including limits on questioning residents, bans on tear gas deployment, and the withdrawal of federal agents from Illinois and Minnesota.
The Trump administration has indicated it will fight the lawsuits vigorously, signaling that enforcement efforts in sanctuary jurisdictions will continue.
As the cases move forward, the legal fight is expected to become a major flashpoint in the ongoing national debate over immigration, federal power, and the role of state governments.
