Andrew Cuomo has been sworn into office as New York's 56th governor in a private ceremony.
The Friday night swearing-in was to become effective at midnight.
Cuomo plans to work Saturday, beginning with a morning cabinet meeting. A short public swearing-in is scheduled for the Democrat's first day on the job, a gesture designed to signal his resolve to tackle New York's historic fiscal and ethical crises.
Cuomo was the state's attorney general. He replaces David Paterson, who took the governor's office in 2008 after Eliot Spitzer resigned in a call girl scandal.
