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

The order explicitly states that the Chicago Police Department will only obey directives from the mayor, rejecting any involvement in federal immigration efforts. Johnson warned of possible militarized enforcement actions, including National Guard deployments and active military presence in the city, while emphasizing that such measures were not requested by local residents. “This president is not going to deputize our police department,” he stated.

The move follows a Department of Homeland Security memo proposing the use of Naval Station Great Lakes as a base for immigration operations near Chicago. Trump has also pledged to deploy National Guard troops to address crime in the city, mirroring past actions in Washington, D.C., and Los Angeles. The White House criticized Johnson’s efforts as “publicity stunts,” contrasting his response with that of Washington, D.C., Mayor Muriel Bowser.

Johnson’s order mandates city departments to challenge federal initiatives that infringe on residents’ rights and demands Trump halt military deployments for immigration enforcement. However, the effectiveness of the measure remains uncertain. The directive reflects broader resistance from Democratic-led cities against Trump’s law enforcement strategies, which include expanding National Guard units to address crime in urban areas.

Trump has faced legal challenges over previous National Guard deployments, including one in Los Angeles aimed at curbing immigration protests. His administration has also accused Illinois Governor JB Pritzker of failing to address Chicago’s rising violence, citing the city’s record-high murder rates.
