Homeland Security Secretary Kristi Noem announced on Sunday that the Trump administration is planning to increase Immigration and Customs Enforcement activities in key cities, including Chicago.

When questioned about the extension of ICE operations in Chicago, Noem informed CBS News’ “Face the Nation” that ongoing ICE activities are already occurring in Chicago, Illinois, and other states, aiming to enforce the law, and the administration plans to boost resources for these operations.

Upon being asked about the specifics of the ICE expansion in Chicago and if it involves deploying National Guard troops for immigration raids and arrests, Noem refrained from details, stating that such decisions rest with President [Donald] Trump, and she won’t discuss the operational plans for other cities.

This statement followed a day after Chicago Mayor Brandon Johnson issued an executive order for the city’s legal team to examine options to oppose any federal law enforcement and National Guard presence in Illinois.

During a Saturday press briefing, Mayor Johnson cautioned that Chicago had received credible intelligence suggesting they could see militarized federal actions in the coming days, not weeks.

Earlier this month, federal law enforcement, including ICE, was directed by the Trump administration to aid Washington, D.C., police with crime reduction efforts, involving the deployment of thousands of National Guard troops in the capital to reduce crime rates.

Following the movement of troops and law enforcement officers to Washington, Trump threatened to send federal officers and troops to other major American cities, including Baltimore.

Later in the Sunday interview, Noem was asked whether Boston would be one of the cities where the federal government would surge immigration enforcement agents.

“There’s a lot of cities that are dealing with crime and violence right now, and so we haven’t taken anything off the table,” she said, adding later: “I’d encourage every single big city — San Francisco, Boston, Chicago, whatever they are — if they want to help make their city safer, more prosperous, allow people the opportunity to walk in freedom like the people of Washington, D.C., are now … they should call us.”

Other Democratic officials, including a group of over a dozen governors, have condemned plans to deploy troops to their states.

In a statement last week, they said, “Whether it’s Illinois, Maryland and New York or another state tomorrow, the President’s threats and efforts to deploy a state’s National Guard without the request and consent of that state’s governor is an alarming abuse of power, ineffective, and undermines the mission of our service members.”

And in an interview that aired Sunday on “Face the Nation,” Illinois Gov. JB Pritzker, a Democrat, said, “We don’t want troops on the streets of American cities. That’s un-American. Frankly, the president of the United States ought to know better.”

Pritzker also accused the Trump administration of targeting states run by Democrats rather than those run by Republicans, telling CBS, “Notice he never talks about where the most violent crime is occurring, which is in red states. … Their violent crime rates are much worse in other places, and we’re very proud of the work that we’ve done.”

Asked whether there are plans in place to deploy troops and federal law enforcement officials to states and cities run by Republicans, Noem said, “Absolutely.”

“Every single city is evaluated for what we need to do there to make it safer. So we’ve got operations that, again, I won’t talk about details on, but we absolutely are not looking through the viewpoint at anything we’re doing with a political lens,” she added.
