New York Daily News Your guide to Manhattan’s Fifth Council District — Upper East Side by Editors

State Assemblyman Micah Kellner, a Democrat once considered the leading candidate for the Fifth District, which covers the upper East Side and Roosevelt Island, is being investigated by the state over allegations he sent sexually suggestive messages to a young staffer.

That cost Kellner the support of Manhattan Borough President Scott Stringer and several unions. Amid the fallout, Ben Kallos, the founder of the Open Government Foundation, is now the front-runner to replace City Councilwoman Jessica Lappin, who's running for Manhattan Borough President.
