Executive summary
The legally binding administration of the mayoral oath in the reporting about Zohran Mamdani is being performed by New York State Attorney General Letitia James at a private midnight ceremony in the Old City Hall subway station, while a separate, ceremonial oath will be given publicly by U.S. Senator Bernie Sanders at City Hall later that day [1] [2] [3]. Contemporary news coverage treats the AG-administered midnight oath as the official transfer of power and the City Hall event as ceremonial and celebratory [4] [5].
1. Who is administering the official midnight oath — and where
Multiple outlets report that the state’s attorney general, Letitia James, will deliver the oath of office to Mamdani during a private, just-after-midnight ceremony at the historic, closed Old City Hall subway station beneath City Hall Park, a setting chosen for its symbolic ties to transit and working New Yorkers [2] [6] [7].
2. Why the Attorney General is highlighted in reports
News organizations consistently name Letitia James as the official administering the first oath, describing that private midnight ritual as the formal act that makes Mamdani mayor when the clock turns — a detail emphasized in both local and national outlets covering the inauguration plans [1] [3] [8].
3. The public, ceremonial swearing-in and who will lead it
Reporting also makes clear that the daytime City Hall event at 1 p.m. is a ceremonial inauguration intended for the public and will feature Sen. Bernie Sanders administering an oath at the public ceremony, with other invited figures—like Rep. Alexandria Ocasio-Cortez—participating in remarks and readings [1] [5] [9].
4. Precedent and practice in coverage: official vs. ceremonial roles
Coverage contrasts the formal legal act at midnight with the larger, symbolic City Hall ceremony: outlets note past mayors have used a range of figures for public inaugurations (citing examples of past mayors and national figures taking public roles) while the initial, formal oath that marks the start of a mayor’s term is often done in a smaller setting—here by the attorney general—followed by a larger public celebration [3] [10] [11].
5. Limits of the reporting and what it does not assert
The available reporting uniformly identifies Letitia James as administering the midnight oath and Bernie Sanders as presiding over the public ceremony, but these articles do not provide a court opinion, statutory text, or authoritative legal memorandum within the provided sources that lays out every legal actor who may constitutionally or statutorily administer a New York City mayor’s oath; therefore, this summary confines itself to who the media report as performing the two January 1 oaths in Mamdani’s inauguration events [2] [4] [6].
6. Political symbolism, choice of officiants and implied agendas
News coverage frames the choice of officiants as politically and symbolically meaningful: naming the state attorney general links the transfer of power to a statewide constitutional officer and highlights institutional legitimacy, while selecting Sanders for the public ceremony underlines Mamdani’s political alliances and the populist, progressive tenor of the public celebration—an intentional pairing of legal formality and political theater documented across outlets [12] [5] [13].
7. Bottom line for readers following the inauguration
Based on reporting across local and national outlets, the legally significant midnight oath will be administered by New York Attorney General Letitia James in the Old City Hall station and the later City Hall oath will be administered ceremonially by Senator Bernie Sanders for the public festivities; the coverage treats the AG’s midnight administration as the formal assumption of office and the City Hall event as the public inauguration [1] [2] [3].
