Chicago Police Supt. Eddie Johnson had “a couple of drinks with dinner” before driving home and slumping over in his vehicle, Mayor Lori Lightfoot disclosed Friday. One day after the police superintendent she inherited requested an internal affairs investigation of himself, Lightfoot refused to say whether Johnson should have been driving or whether he should have been given a sobriety test. Lightfoot told the Chicago Sun-Times she would await the outcome of the internal investigation before determining whether the rules were bent to protect the boss and whether to hold Johnson responsible.
