Chicago Mayor Brandon Johnson on Saturday signed an executive order targeting President Donald Trump’s threatened federal takeover of the Windy City’s police to tackle crime and illegal immigration. 

Trump earlier this month announced a temporary government takeover of Washington, D.C.’s police force, authorizing hundreds of federal troops to assist understaffed city police in an effort to combat crime in the country’s capital. The president has suggested he could send troops to Chicago as the next city in an anti-crime initiative, sparking outrage from local and state officials.
