CHICAGO (WLS) -- A judge postponed a ruling Monday on whether a special prosecutor is needed to investigate alleged crimes tied to "Operation Midway Blitz."
Attorneys and advocacy groups say federal agents from U.S. Immigration and Customs Enforcement and U.S. Department of Homeland Security violated state law during their immigration crackdown across the Chicago area.
They argue those agents have not been properly investigated by the Cook County State's Attorney's Office.
Now, they're asking for a special prosecutor.
Judge Erica Reddick heard arguments last month and is expected to issue a ruling Monday.
However, the judge said she was not ready to rule and is expected to make a ruling on May 21.

In a statement, the Cook County State's Attorney's Office said:
"The State's Attorney has repeatedly condemned the tactics used by the Trump administration and during Operation Midway Blitz, denouncing the abhorrent conduct we have all witnessed.
As we have argued in court, the CCSAO must follow the law and the facts to protect the integrity of our prosecutions and ensure that any resulting conviction will stand.
Illinois Supreme Court precedent makes it clear that law enforcement must initiate criminal investigations and then can refer the case to prosecutors for charging decisions and investigative support.
The petition seeking a special prosecutor is frivolous, contains baseless allegations and gross misrepresentations of the law."
