A little over a dozen aldermen showed up for budget hearings Friday morning, which included swan song testimony for City Clerk Susana Mendoza, who is widely expected to win her campaign for State Comptroller on November 8. Aldermen in the Budget Committee, helmed by Vice Chair Jason Ervin (28) for the fourth day in a row, also lightly questioned the Public Library commissioners, mostly asking for further details on how they can obtain additional library services.
