Chicago Mayor Brandon Johnson has issued an executive order outlining measures for city officials to counteract a potential immigration crackdown by the Trump administration. The directive instructs city agencies and local law enforcement to reject collaboration with federal agents on joint operations, including civil immigration enforcement.

The order specifies that the Chicago Police Department will only follow orders from the mayor, rejecting participation in federal-led patrols or arrest efforts. Johnson emphasized resistance to federal overreach, stating, “This president is not going to come in and deputize our police department.”

The move follows a Department of Homeland Security memo proposing the use of Naval Station Great Lakes as a base for immigration operations in Chicago, potentially impacting nearby suburbs. Trump has also pledged to deploy National Guard forces to address crime in the city, mirroring actions taken in Washington, D.C., and Los Angeles.

Johnson’s order urges city departments to pursue all legal avenues to block federal efforts that violate residents’ rights. It calls on Trump to halt military deployments for immigration enforcement, though its effectiveness remains uncertain.

The mayor has warned of an influx of federal agents “as early as Friday,” citing rising violence in Chicago. Meanwhile, the White House criticized Johnson’s actions as political posturing, contrasting them with the response of Washington, D.C., Mayor Muriel Bowser to similar federal measures.
