The mayor’s office was being tight-lipped about what Lightfoot might ask Buttigieg, but the event is part of a series that pairs 11 mayors across the United States with individual Democratic candidates to discuss the needs of American cities. Expect there to be some prompting about what the South Bend, Indiana, mayor has done to make his city better and how that experience would translate if he were president. The one-on-one interviews got underway this afternoon, but the two mayors — Lightfoot and Buttigieg — won’t take the stage until approximately 7:30 p.m. You can watch it livestreamed here.
