Chicago federal intervention: Tracking surge in immigration enforcement operations | Live updates

After weeks of verbally condemning the aggressive federal immigration crackdown in the Chicago region, Illinois lawmakers approved legislation banning civil immigration arrests in and around state courthouses early Friday morning.

House Bill 1312, among other provisions, would also allow Illinois residents to sue immigration agents who violate their constitutional right to due process and protection against unreasonable searches and seizures.

It heads to Democratic Gov. JB Pritzker's desk after clearing the Illinois Senate 40-18 and the Illinois House 75-32 in the waning hours of their annual fall veto session.

Evanston Township High School is implementing a closed campus protocol Friday due to federal activity reported in the area, the school said just before noon on X.

All students must remain on campus during lunch and free blocks.

There is no current threat to the school and federal authorities are not on school grounds, school officials said.

"While we currently have no indication that federal activity will occur on our campus, we are implementing this proactive measure to help ensure the safety and well-being of all students," the school said.

An emergency proposed class-action lawsuit has been filed against the U.S. Department of Homeland Security (DHS) over "abusive and cruel" conditions for people who have been detained and held inside Immigration and Customs Enforcement (ICE)'s processing center in the village of Broadview.

The lawsuit was filed on behalf of two people who were detained by ICE in the past two days and held at the Broadview facility.

Attorneys with the ACLU of Illinois and the MacArthur Justice Center say U.S. Immigration and Customs Enforcement agents have denied people being held at the Broadview facility private calls with attorneys and have blocked members of Congress, faith leaders and journalists from entering the building, creating a "black box" they say has allowed authorities to act "with impunity."

Illinois state lawmakers are also looking to impose restrictions on ICE activities in places like hospitals and courthouses, pushing ahead with legislation to curb illegal ICE activity.

"The piece that I've introduced initially creates a private right of action for anyone who has been harmed, anyone whose constitutional rights have been violated by people conducting immigration actions, will be able to go to court and seek a remedy," Illinois State Senate President Don Harmon said.

The bill would also create safe spaces from ICE in courthouses, along with daycare centers and universities, as well as hospitals. The measure gained urgency after the viral video of Chicago Alderperson Jessie Fuentes being arrested in a hospital confronting ICE over agents' authority to arrest someone seeking treatment.

"This bill is a statement on behalf of the legislature to say that what ICE is doing is unacceptable," said State Sen. Celina Villanueva, who represents part of Chicago's Southwest Side.

There was some urgency to get the measure passed before the end of the night Thursday, because it is the final day of the veto session.
