Todd Lyons, acting director of Immigration and Customs Enforcement, called on Illinois to honor immigration detainers in a letter to Democratic state Attorney General Kwame Raoul on Monday.

As the Trump administration continues its surge in immigration enforcement in the Chicago area through Operation Midway Blitz, it continues to clash with Gov. JB Pritzker‘s (D-IL) administration as Pritzker attempts to stiff-arm what he has called a federal “power grab.” The Department of Homeland Security said the state’s refusal to honor immigration detainers has led to the release of 1,768 illegal immigrants from criminal custody in the state since Jan. 20.
