The Democrat's team is planning two separate swearing-in ceremonies Thursday — a small, private one with his family in an old subway station around midnight, followed by a large event in the afternoon that will include a public block party outside City Hall.
For his part, Mamdani will take his initial oath at the former City Hall subway station in Manhattan — one of the city's original stops on its subterranean transit system, known for its tiled arches and vaulted ceilings.
New York Attorney General Letitia James, a political ally and notable foe of President Donald Trump, will administer the oath of office.
On Thursday afternoon, Mamdani will be sworn in again, this time by U.S. Sen. Bernie Sanders, one of his political heroes, on the steps of City Hall in a ceremony scheduled to kick off at 1 p.m. U.S. Rep. Alexandria Ocasio-Cortez, another political ally, will deliver opening remarks.
