Hours after 34-year-old democratic socialist Zohran Mamdani was elected New York City’s next mayor, his victory speech taunted President Donald Trump — “Turn the volume up” — and pledged an immigrant-led resistance. Trump, who watched, hit back from a Miami business conference, saying the US had lost “sovereignty,” labeling the mayor-elect a communist, and marking the anniversary of his win over Kamala Harris. He threatened to pull federal support for the city in a Fox interview, after months undermining Mamdani while boosting Andrew Cuomo over Republican Curtis Sliwa.
