An attorney for the Trump administration told a federal judge Thursday that it’s “wrong to allege” a recent immigration enforcement surge in the Chicago area—known as Operation Midway Blitz—is over. However, the administration declined to say whether federal agents plan to return to the city.

The comments came during a hearing before U.S. District Judge Sara Ellis. The case stems from a lawsuit filed earlier this fall by protesters, clergy, and journalists who accused federal immigration agents of using excessive force, including tear gas, during demonstrations.

Last month, Judge Ellis issued an order limiting agents’ use of force after reviewing video of a Border Patrol commander tackling a protester and deploying tear gas. But the 7th Circuit Court of Appeals quickly put that order on hold, siding with the Trump administration.

Meanwhile, more than 200 Border Patrol agents who had been stationed in Chicago have since left for North Carolina, and National Guard members deployed to support them were also sent home.

Attorneys for the plaintiffs argued the agents’ departure meant the lawsuit was no longer necessary, but the administration pushed back, saying the operation is not definitively over.

When asked whether agents would return to Chicago, the Justice Department declined to give any timeline.

Judge Ellis expressed concern about the possibility of future force, saying that after watching the videos and testimony, she “strongly disagrees” with the government’s claim that no agents acted improperly.

The lawsuit is now expected to be dismissed, and upcoming court dates tied to the case will be canceled.
