Johnson, a 47-year-old Cook County Commissioner, becomes the 57th mayor of the third-largest U.S. city, after incumbent Lori Lightfoot was eliminated from the race in February. Vallas called for more police officers, while Johnson suggested more mental health support and opportunities for young people. Johnson, a former Chicago teacher and union organizer, says he will promote 200 new detectives from the existing pool of police officers.
