New York City's Fire Department Commissioner Robert Tucker has resigned, with his departure coming just hours after Zohran Mamdani was elected as the city's new mayor. Tucker, who is Jewish, will officially step down on December 19 and is expected to return to his previous role leading a private security firm. The reasons for his resignation remain unclear, and there were reportedly no discussions with Mamdani's team about Tucker staying on under the new administration.

Mamdani, who will become the city's first Muslim mayor, won a decisive victory with a campaign focused on affordability and populist policies such as free public buses and rent freezes. His win marks a significant political shift for New York, and he used his victory speech to address both his supporters and critics, including former president Donald Trump. The mayoral race saw record voter turnout, with over two million votes cast before polls closed.
