Contentious supervisors' hearing, featuring Mayor Breed on opioid crisis, ends abruptly

City leaders in San Francisco were part of a contentious hearing Tuesday that ended abruptly. The rare open-air meeting focused on the city's drug market and fentanyl crisis. Mayor London Breed made an appearance as requested by the board of supervisors. The meeting quickly devolved into heckling and even a brick thrown before it was moved back indoors.
