NEW YORK (WABC) -- Zohran Mamdani was officially sworn in as mayor of New York City just after midnight Thursday, but politicians and other supporters are gathered later in the day at City Hall for a larger ceremony.
Mamdani is the city's first Muslim mayor, its first of South Asian descent and the first to be born in Africa. At 34, he is also the city's youngest mayor since the late 19th century.
The democratic socialist takes office after an historic campaign made "affordability" a national buzzword across the political spectrum.
U.S. Sen. Bernie Sanders administered the public ceremonial oath of office to Mamdani at today's event, broadcast on Channel 7 and streaming on ABC 7 New York.
At midnight on Jan. 1, Zohran Mamdani will take the oath of office for New York City mayor, surrounded by just his family.
The ceremony will take place at the Old City Hall Station -- a now out-of-commission subway stop that dates back to 1904 and was one of New York's 28 original subway stations.
Mamdani says the location reflects his commitment to the working people who keep the city running.
Broadway between Worth Street and Battery Place and Liberty Street between Church Street and Broadway will be closed Thursday for the inauguration at the discretion of the NYPD.

At 1 p.m., Mamdani's ceremonial swearing-in will take place on the steps of City Hall where Sen. Bernie Sanders will administer the Oath of Office.
Congresswoman Alexandria Ocasio-Cortez will deliver the opening remarks and acclaimed poet Cornelius Eady will read an original poem.
Traditionally, this ceremony is held for 4,000 ticketed guests, but Mamdani is planning a free and public block party on Broadway along the Canyon of Heroes.
As a new mayor's term begins immediately with the new year, it has been customary for the city's incoming leaders to hold two events.
Outgoing mayor Eric Adams held his initial swearing-in at Times Square shortly after the famous ball drop, while Adams' predecessor, Bill de Blasio, took his first oath at home in Brooklyn.
