MTA chairman Joe Lhota resigns

MTA chairman Joe Lhota resigned on Friday. Lhota, 64, was appointed chairman last year amid increasing problems on the city's aging subway system.

It was his second stint as MTA chief.

New York Gov. Andew Cuomo said Lhota had stabilized the system, appointed a new leadership structure to overhaul the MTA and "led with a steady hand during some of the agency's most challenging moments."

MTA Vice Chairman Fernando Ferrer is now the acting chairman.
