The mayor of Chicago has signed an order detailing how the city will resist a potential immigration crackdown threatened by the Trump administration.

We do not need nor want an unconstitutional and illegal military occupation of our city, said Mayor Brandon Johnson, a Democrat. The order directs city agencies on how to respond to possible immigration enforcement actions.

Trump has already deployed about 2,000 troops to Washington DC, and has threatened to extend the order to Chicago, which he describes as a mess. There are also reports the administration is planning a surge of federal immigration agents into the city.

A White House spokesperson described Johnson's order as a publicity stunt. The order demands that Trump and federal agents stand down from any attempts to deploy the US Armed Forces in the city.

Local officials assert that more than one in five residents is an immigrant, with over half hailing from Latin America. Johnson indicated that city officials would help residents understand their rights during immigration encounters while ruling out local officers joining federal patrols.

This development adds another chapter to the escalating feud between local government and a White House adamant about enforcing strict immigration policies.
