Story highlights

“The Trump administration’s illegal actions already have subjected and are subjecting Illinois to serious and irreparable harm,” the lawsuit stated.

Illinois filed a lawsuit Monday (Oct 6) in an attempt to block the deployment of National Guard troops in Chicago, a city branded as a “war zone” by US President Donald Trump. Meanwhile, a federal judge blocked a similar deployment of troops to Portland, Oregon, ordered by the Trump administration as part of its crackdown against crime and illegal immigrants.

“The American people, regardless of where they reside, should not live under the threat of occupation by the United States military, particularly not simply because their city or state leadership has fallen out of a president’s favor,” the Illinois Attorney General’s Office wrote in the filing. The lawsuit names President Donald Trump, Homeland Security Secretary Kristi Noem, Defense Secretary Pete Hegseth and Army Secretary Daniel Driscoll as defendants.

“The Trump administration’s illegal actions already have subjected and are subjecting Illinois to serious and irreparable harm,” the suit added.

The lawsuit comes a day after a federal judge temporarily blocked the US president’s order to send troops to Oregon’s biggest city, Portland. Over the weekend, Trump authorised deploying 700 National Guard soldiers to Chicago despite mounting opposition from the state’s Democratic leaders, who warned of chaos as a result of the administration’s decision.

“Far from promoting public safety in the Chicago region,” the state authorities wrote in the lawsuit, adding that Trump’s “provocative and arbitrary actions have threatened to undermine public safety by inciting a public outcry.”

“Illinois asks this Court to declare these actions unlawful and enjoin them, immediately as well as permanently,” they further added.

Last week, Trump told a gathering of military leaders that they should use “dangerous” American cities as “training grounds,” sparking outrage. Speaking at the rare meeting called by Pentagon chief Pete Hegseth at Marine Corps Base Quantico in Virginia on September 30, Trump said that the move was necessary as the US is facing a “war from within”.
