Donald Trump lashed out at Chicago’s leadership and launched “Operation Midway Blitz” as part of a federal intervention after a violent weekend left six people dead and a dozen others wounded.

The former president criticized Illinois Gov. JB Pritzker and Chicago Mayor Brandon Johnson, accusing them of failing to protect residents. He claimed he wants to help the city, but made it clear who he believes should suffer. The post came as Chicago braces for the influx of federal agents and troops. Trump’s Border Czar, Tom Homan, told CNN that cities with sanctuary policies should expect enforcement soon. Over the weekend, community organizers in Chicago distributed flyers to inform residents of their rights in the event of immigration raids. Several public events were canceled as anxiety grew over a potential federal operation. Trump stoked that tension further by posting a photo of himself with the city skyline behind him, captioned: “Chicago about to find out why it’s called the Department of WAR.”
