What happened

Key facts

  • On October 29, 2026, the Trump administration urged the U.S. Court of Appeals for the Seventh Circuit to revive its lawsuit against Illinois and Chicago.
  • The lawsuit is among several similar cases brought by the Trump administration; the source says those cases have not succeeded in federal district courts.

The brief

The Trump administration has asked the U.S. Court of Appeals for the Seventh Circuit to revive its lawsuit against Illinois and Chicago, arguing that their immigration policies obstruct federal enforcement. The Washington Examiner reported that the administration brought the case as part of a wider set of lawsuits challenging policies it calls “sanctuary” measures.

The administration’s argument concerns federal custody of people held by state authorities. Talent said that if Congress permits federal officials to assume custody before a state incarceration period ends, states cannot invoke the 10th Amendment to refuse a transfer and release someone from custody.

His argument ties the federal government’s claimed authority to congressional authorization and the timing of state incarceration. Talent also argued that states may not actively obstruct federal officials seeking to carry out Congress’s purposes of taking people into custody and removing them.

That is the administration’s position in the dispute; the account does not describe a court ruling resolving the legal question in this appeal. Hemmer, speaking for Illinois, said the state had chosen not to require its police officers to assist federal authorities with civil immigration enforcement.

He characterized that choice as a decision about whether state officers must take part in federal enforcement, rather than describing Illinois as preventing federal officers from acting themselves.

The case is one of several similar lawsuits the Trump administration has brought against cities and states with policies it labels “sanctuary.” The Washington Examiner said those cases have not succeeded in federal district courts, placing the current request within a broader series of legal challenges that have so far failed at that level.

The appeal asks the Seventh Circuit to revive the lawsuit; the available account does not state what the court decided.

The central dispute presented is whether Illinois and Chicago may decline to have state officers assist with civil immigration enforcement, and whether that choice unlawfully obstructs federal action under the administration’s reading of congressional authority.

Why it matters

  • Illinois and Chicago’s policies are the subject of a federal lawsuit over whether state and municipal authorities must assist with civil immigration enforcement.
  • The dispute centers on the mechanism of custody transfer: Talent argued federal officials may assume custody before a state incarceration period ends if Congress authorized it.
  • Hemmer said Illinois does not require state police officers to assist federal civil immigration enforcement, identifying the state’s position on officer participation.

What to watch next

  • Whether the U.S. Court of Appeals for the Seventh Circuit revives the Trump administration’s lawsuit.
  • How the court addresses Talent’s argument about federal custody authority and the 10th Amendment.
  • Whether the appeal addresses Hemmer’s description of Illinois’s choice not to require state police assistance.
