'Welcome to a New Era for NYC': Zohran Mamdani Sworn In as New York City Mayor

Democratic socialist Zohran Mamdani was sworn in as New York City's mayor early Thursday inside an abandoned subway station, capping off the rise to power of a former state assembly member whose laser focus on affordability, willingness to challenge establishment corruption, and adept use of social media inspired the electorate—including many previous nonvoters.

Mamdani's choice of location for the swearing-in ceremony, led by New York Attorney General Letitia James, symbolized his commitment to restoring a city "that dared to be both beautiful and build great things that would transform working people’s lives," the mayor said in a statement.

During his campaign, Mamdani pledged to pursue a number of ambitious changes that he and his team will now begin the work of trying to implement, from fast and free buses to a $30 minimum wage to universal childcare—an agenda that would be funded by higher taxes on large corporations and the wealthiest 1% of New Yorkers.

“Happy New Year to New Yorkers both inside this tunnel and above,” Mamdani said in brief remarks at the ceremony. “This is truly the honor and privilege of a lifetime.”

Much of Mamdani's agenda would require action from the city legislature. But in the weeks leading up to his swearing-in, members of Mamdani's team scoured city statutes looking for ways Mamdani could use his mayoral authority to lower prices quickly.

In an interview with Vox earlier this week, Mamdani said that enacting his agenda is "not just critically important because you’re fulfilling what animated so many to engage with the campaign, to support the campaign, but also because of the impact it can have on New Yorkers’ lives."

"There’s a lot of politics where it feels like it’s a contest around narrative, that when you win something, it’s just for the story that you can tell of what you won, but so many working people can’t feel that victory in their lives," he said. "The point of a rent freeze is you feel it every first of the month. The point of a fast and free bus is you feel it every day when you’re waiting for a bus that sometimes never comes. The point of universal child care is so that you don’t have to pay $22,500 a year for a single toddler."

Prior to Thursday's ceremony, former Democratic Mayor Eric Adams spent his final hours on a veto spree, blocking 19 bills including worker-protection legislation.

City & State reported that "among the 19 pieces of legislation that received a last-minute veto was a bill that would expand a cap on street vending licenses, a bill that aims to protect ride-hailing drivers from unjust deactivations from their apps, a bill that would prohibit federal immigration authorities from keeping an office at Rikers Island, and a bill that would grant the Civilian Complaint Review Board direct access to police body-cam footage."

Bhairavi Desai, executive director of the New York Taxi Workers Alliance, said in a statement that "Mayor Adams' last stand to steal protections from workers can’t dampen our hope for a better New York City under the leadership of Zohran Mamdani... and his pro-worker appointees, including Julie Su."
