Chicago’s mayor issued a warning to residents spending long periods of time outside their homes as the city tries to stem the spread of the coronavirus.

Mayor Lori Lightfoot said Wednesday that Chicagoans need to follow the statewide “stay at home” order issued by Gov. J.B. Pritzker last week. She said residents should “only go out for the essentials” and warned that those violating the rules could wind up in trouble.
