Chicago is moving to put federal immigration agents under a new kind of spotlight.

On Saturday, Mayor Brandon Johnson signed an “ICE On Notice” executive order directing Chicago police to investigate alleged illegal activity by federal immigration officers and share findings with prosecutors and the public.

“This executive order will make Chicago the first city in the country to set the groundwork to prosecute ICE and Border Patrol agents for criminal misconduct,” the mayor said.

“Nobody is above the law. There is no such thing as ‘absolute immunity’ in America,” he said. Johnson then explained that the “lawlessness” of the current administration’s “militarized immigration agents puts the lives and well-being of every Chicagoan in immediate danger. With today’s order, we are putting ICE on notice in our city.” 

Johnson went on to share that his beloved city will not sit idly by as federal agents flood communities and terrorize residents.

"If the federal government will not hold these rogue actors accountable, then Chicago will do everything in our power to bring these agents to justice," Johnson said.

Under the order, if Chicago Police Department officers see or receive reports that federal agents may have broken state or local laws, they must document what happened, preserve body-camera footage, and identify the agents involved. 

Any evidence of alleged felony violations must be sent to the Cook County State’s Attorney’s Office, and CPD must also release data on alleged violations by federal immigration officers. 

Though the order stops short of directing Chicago police to arrest federal personnel. CPD officials were given 30 days to write a policy to put all of this into practice.

City officials say the move is a direct response to recent shootings and killings linked to immigration enforcement actions in the Chicago area and beyond. Advocates argue the order finally creates a way to gather and preserve evidence when things go wrong. But the city’s police union blasted the move as “political bluster” and says it will be looking at any legal risk this could create for officers.

​"But whether or not the federal government will respect our local government and respect how our state functions, that's gonna be interesting to see how that plays out," said Katarina Ramos with the National Immigrant Justice Center, according to ABC7.
