Lori Lightfoot will be Chicago's first black female mayor
Former federal prosecutor Lori Lightfoot was elected Chicago mayor on Tuesday, becoming the first black woman and first openly gay person to lead the nation's third-largest city.
Lightfoot defeated Toni Preckwinkle, who served in the City Council for 19 years before becoming Cook County Board president.
Lightfoot promised to rid City Hall of corruption and help low-income and working-class people who she said had been "left behind and ignored" by Chicago's political ruling class. It was a message that resonated with voters weary of political scandal and insider deals, and who said the city's leaders for too long have invested in downtown at the expense of neighborhoods.
