The mayor of Chicago pushed back on Saturday against what he described as the “out-of-control” plan by the Trump administration to send federal officers into the nation’s third-largest city, a move that could take place within days, AP reported.

An executive order signed by Mayor Brandon Johnson bars the Chicago Police Department from assisting federal authorities with civil immigration enforcement or related patrols, traffic stops, and checkpoints during the surge.

The mayor instructed all city departments to safeguard the constitutional rights of Chicago residents “amidst the possibility of imminent militarised immigration or National Guard deployment by the federal government”, reported AP.
