In a balcony at Carnegie Music Hall in Oakland on Monday afternoon, four previous Pittsburgh mayors sat together, representing more than two decades of the city’s past. On the stage below them stood the city’s future: Corey O’Connor, sworn in as Pittsburgh’s 62nd mayor. O’Connor, riding the high of the Pittsburgh Steelers clinching a playoff spot this year and carrying on a family legacy, promised renewed optimism, progress and hope for the city. “It is the greatest honor to serve as your mayor,” O’Connor said Monday. “I’m humbled to take on this role and I will fight for this city each and every day.” Read more about Pittsburgh’s newest mayor at the link in our bio. 📝: Hallie Lauer/Post-Gazette 📸: Steve Mellon/Post-Gazette #Pittsburgh #PittsburghMayor
