President Donald Trump is preparing to send members of the Texas National Guard as well as “armed military personnel” to Chicago, Gov. JB Pritzker said Tuesday.

The Department of Justice on Tuesday filed a lawsuit against Gov. JB Pritzker, Illinois Attorney General Kwame Raoul and the state itself.

The order comes after California sued, saying the troops sent to Los Angeles over the summer were violating a law that prohibits military enforcement of domestic laws.

“We do not want to see tanks in our streets,” Mayor Brandon Johnson said. “We do not want to see families ripped apart. We do not want grandmothers thrown into the back of unmarked vans. We don’t want to see homeless Chicagoans harassed or disappeared by federal agents.”

The operation in the country’s third-largest city is expected to last about 30 days and could start as early as Sept. 5, a Department of Homeland Security official told The Associated Press on Friday.

President Donald Trump and his aides have repeatedly slammed Chicago over policies that limit cooperation between local authorities and federal immigration enforcement.

If Trump federalizes the National Guard or sends additional ICE agents to Chicago, all Chicago Police officers will be required to wear their uniforms and will not be dispatched to immigration enforcement operations, Supt. Larry Snelling said Thursday.

Gov. JB Pritzker said he’s received no word from the Trump administration following reports it intends to use the Naval Station Great Lakes outside Chicago to house federal immigration agents or National Guard troops.

Illinois Secretary of State Alexi Giannoulias raised concerns and announced Monday that an audit found Customs and Border Protection had accessed Illinois data, although he didn’t say that the agency was seeking immigration-related information. A 2023 law the Democrat pushed bars sharing license plate data with police investigating out-of-state abortions or undocumented immigrants.

Gov. JB Pritzker vowed Monday to stop President Donald Trump from deploying the National Guard to Chicago, dismissing Trump’s latest pledge to combat crime as cover for an unconstitutional federal overreach.

U.S. District Judge William Orrick issued an injunction late Friday to that will prevent the Trump administration from blocking funding for some of the nation’s largest cities, including Chicago, Los Angeles, Denver, Boston and Baltimore.

With lots of money approved by Congress this summer starting to flow into ICE, the agency is in midst of a huge hiring effort as it aims to get thousands of new deportation officers into the field in the coming months.

Since President Donald Trump took office in January, his administration has thus far focused on deporting migrants illegally in the United States as well as holders of student and visitor exchange visas.

The Adams County Sheriff’s Office in western Illinois has transferred at least two men into U.S. Immigration and Customs Enforcement custody, in apparent violation of the state’s TRUST and Way Forward Act, according to a lawyer who helped provide technical support for the legislation.

The U.S. Department of Health and Human Services first handed over the personal data on millions of Medicaid enrollees in a handful of states in June. After an Associated Press report identified the new policy, 20 states filed a lawsuit to stop its implementation.

The Miami Correctional Facility in Miami County, Indiana, is allowing the federal government to detain immigrants. It’s located about 130 miles southeast of Chicago’s border with Indiana and 70 miles north of Indianapolis.
