ICE agents are expected to be joined by officials from several more agencies in the multi-day operation that will soon spread across the country, seemingly beginning with Democratic-run states and cities.

The Chicago operation is part of a broader effort to beef up ICE in terms of resources and agents, as the Trump administration launches its nationwide crackdown toward fulfilling President Donald Trump‘s vow to deport one million people.  

Dangerous Criminal Aliens? The Governor Begs To Differ

Illinois Gov. JB Pritzker (D) told CNN's Dana Bash on Sunday that he too wants violent criminals out of the country, but he expressed concern about how the Trump administration is carrying out operations.

"If that's who they're picking up, we're all for it." But, Prizker said, “they're going after people who are law-abiding, who are holding down jobs, who have families here, who may have been here for a decade or two decades. Why are we going after them? These are not people who are causing problems in our country.”
