New York City Mayor Zohran Mamdani began his first full day in office with a subway commute from his Queens apartment, a move documented by media and neighbors. The 34-year-old democratic socialist, whose election is seen as a progressive milestone, also signed orders and made appointments. His initial actions included revoking a previous administration's order on antisemitism, which drew backlash from some Jewish groups, while his relatable commute echoed that of past mayors.
