New York City is preparing for a historic and symbolic political milestone as Senator Bernie Sanders will publicly swear in Mayor-Elect Zohran Mamdani on January 1 at City Hall Plaza. The ceremony — expected to draw at least 4,000 invited guests — will mark the beginning of a new progressive chapter in NYC leadership. br br Before the public ceremony, New York Attorney General Letitia James will administer a private midnight family oath, underscoring the formal transfer of power. The day will conclude with a massive seven-block Broadway inauguration block party, celebrating what Sanders calls a “new generation of progressive leadership.” Mamdani, 34, will move into the historic Gracie Mansion with his wife as he officially takes charge of New York City. br br #BernieSanders #ZohranMamdani #NYCMayor #NYCInauguration #NewYorkPolitics #CityHallNYC #LetitiaJames #ProgressiveLeadership #NYCNews #BreakingNews #BernieSwearsInMamdani #NYCBlockParty #GracieMansion #NYCEvents #January1Ceremony #NewYorkCityUpdates #PoliticalNews #USPoliticsbr br ~ED.103~HT.
