Zohran Mamdani to be sworn in as New York City mayor by Sen. Bernie Sanders and AG Letitia James

James will formally swear in Mamdani at midnight when his term officially begins, and Sanders will oversee the mayor-elect's ceremonial swearing-in later that day.

Incoming New York City Mayor Zohran Mamdani will be sworn into office in January by state Attorney General Letitia James and Sen. Bernie Sanders, I-Vt., his fellow democratic socialist.

Sanders will oversee the mayor-elect's ceremonial swearing-in at a New Year's Day block party, while James will formally swear in Mamdani at midnight when his term officially begins.

In a news release announcing the events, the transition noted that Sanders' “unapologetic progressive values inspired Zohran to run for office in the first place.”
