Zohran Mamdani sealed his mayoral victory in New York City with gains in several key areas. Here are some notable takeaways.

In a fiery speech after his win, the next mayor of New York warned Trump that the city will stand united: "To get to any of us, you will have to get through all of us."

Mamdani, who will be New York City’s first Muslim mayor, defeated former governor Andrew Cuomo and Republican Curtis Sliwa. He will replace Mayor Eric Adams.

Jewish leaders had a mixed reaction to the election of Zohran Mamdani, who has repeatedly criticized Israel’s treatment of Palestinians and its conduct during the war in Gaza.

New York City Mayor-elect Zohran Mamdani wasted no time calling out President Donald Trump, formally kicking off the battle that will likely define relations between the 34-year-old mayor and the president whose celebrity is tied to the city.

A diverse but younger-skewing crowd filled the Paramount Theater in Brooklyn with enthusiasm, dancing to hip hop and celebrating the socialist's win.

Hundreds of volunteers join the first town hall gathering hosted by Mr. Mamdani and the New York City chapter of the Democratic Socialists of America. Days later, canvassers begin field work for Mr. Mamdani, a longtime D.S.A. member who was endorsed by the local chapter.
