Overview
- New York Attorney General Letitia James administered the private oath just after midnight in the disused Old City Hall subway station.
- Mamdani became the first NYC mayor to swear on the Qur'an, using multiple copies including his grandfather’s and a volume associated with historian Arturo Schomburg.
- The public inauguration on the City Hall steps is scheduled for 1 p.m. ET, with Bernie Sanders administering the oath and Alexandria Ocasio-Cortez presenting him.
- City organizers set a free Broadway block party with large screens and viewing zones from Liberty to Murray Streets, plus about 4,000 seated guests near City Hall.
- Mamdani is launching an affordability agenda that includes a rent freeze for many rent‑stabilized units, 200,000 affordable homes, universal childcare, public supermarkets and free buses, proposals that face funding and authority hurdles even as he retains NYPD Commissioner Jessica Tisch.
