As Chicago Mayor Lori Lightfoot’s two-year anniversary approaches, top-level vacancies are mounting: ‘This has been a very tough year, I think, on a lot of people’

At least a dozen top people in Chicago Mayor Lori Lightfoot's office have resigned or said they’re on their way out since late last year. Several positions have remained unfilled for weeks or months.
