Operation Midway Blitz, a federal immigration enforcement campaign in the Chicago area, ended on November 14, 2025, after running for 68 days—not an ongoing operation. During that period, ICE officers detained 3,841 people, but according to a Chicago Sun-Times analysis, 81% had no criminal convictions, contradicting Department of Homeland Security claims to target "the worst of the worst." Current low-profile ICE enforcement activity has resumed in Chicago neighborhoods as of September 2026, separate from the Blitz campaign. This article clarifies what the Blitz was, what evidence shows about its actual impact, and what is happening in Chicago's immigration enforcement landscape today.

What Operation Midway Blitz Actually Was
The operation ran from September 8 through November 14, 2025, as a federal initiative focused on immigration enforcement in the Chicago metropolitan area. The Department of Homeland Security announced the campaign and characterized it as targeting individuals with criminal records.
In those 68 days, ICE detained 3,841 people across the region. However, the scale of the campaign and its public visibility set it apart from routine enforcement—high-profile arrests, visible presence in multiple neighborhoods, and sustained federal resources marked it as distinct from quieter operations. The Trump administration portrayed the Blitz as a decisive response to sanctuary policies in Illinois and Chicago. The intensity and timing of the campaign drew immediate attention from civil rights organizations, local officials, and business groups concerned about the operation's conduct and collateral effects.
Who Was Arrested and Why It Matters
The actual composition of those detained contradicted the stated mission. According to the Chicago Sun-Times analysis, 81% of the 3,841 people arrested during Operation Midway Blitz had no criminal convictions at all. This finding is critical because it shows the Blitz caught far broader populations than serious offenders—people detained for immigration violations alone, without criminal history.
By contrast, a Sun-Times and WBEZ analysis found that quieter, lower-profile enforcement efforts before and after the Blitz were more successful at detaining convicted murderers, rapists, and violent offenders. This suggests that visible, large-scale sweeps may have actually been less effective at addressing violent crime than less publicized enforcement work.
Civil Rights Violations and Use of Force
An Illinois Accountability Commission investigation documented serious misconduct during the operation. The investigation found that ICE officers used chemical weapons over 60 times and engaged in "unjustified and excessive" force that violated constitutional rights, according to ABC7 Chicago's reporting of the commission's findings. These findings raise liability questions and cast the campaign's methods in serious question.
The pattern of force reflects a broader concern about enforcement tactics that go beyond immigration law into potential civil rights territory. Documented chemical weapon use during immigration arrests, particularly when 81% of those arrested had no criminal background, suggests enforcement was not calibrated to the actual threat posed.
Legal Challenges and Economic Costs
Illinois and Chicago filed a federal lawsuit in response to the operation. The states alleged that the Trump administration "unleashed an organized bombardment" designed to coerce them into abandoning sanctuary policies, according to ABC7 Chicago. U.S. District Judge Sara Ellis will rule on the state's motion to dismiss the lawsuit on November 17, 2026, a decision that may clarify the legal boundaries of how federal enforcement can target state policy positions.
The operation also imposed measurable economic harm. Operation Midway Blitz cost Chicago-area businesses $1.2 billion in foregone commercial activity, primarily affecting restaurants and retail, according to an economic analysis cited by The Hill. The business disruption reflects not only direct arrests but also the chilling effect of visible federal enforcement on consumer activity and workforce presence.
Current Enforcement and What's Different Now
While Operation Midway Blitz itself ended in November 2025, low-profile ICE enforcement resumed in Chicago in September 2026 under different operational terms. Agents have been reported near Skokie and in Gage Park, Pilsen, and Humboldt Park neighborhoods as of September 20, 2026, according to NBC Chicago and the Daily Northwestern. This activity is distinctly different from the Blitz—quieter, less centrally coordinated, and lower profile.
The contrast matters because the evidence suggests this quieter approach may be more effective at apprehending individuals with genuine criminal backgrounds. Readers concerned about immigration enforcement in Chicago should monitor both ongoing federal activity and the outcome of the pending lawsuit, which may reshape how federal and state authorities interact on immigration policy.
