Zohran Mamdani was sworn in as New York City mayor in the first minutes of the New Year at the historic City Hall subway station, with his wife Rama Duwaji standing by his side. The oath, in which he pledged to support the Constitution of the United States and the laws of New York, was administered by New York State Attorney General Letitia James. "Happy New Year to New Yorkers, both inside this tunnel and above," said Mamdani, standing beneath a vaulted ceiling with the words City Hall over his head. "This is truly an honor and a privilege of a lifetime."
