Zohran Mamdani was elected the 111th mayor of New York in a historic victory that will put an avowed democratic socialist in charge of the city that serves as the capital of global finance. One of his first challenges as mayor will be managing the city's relationship with the White House. President Donald Trump has repeatedly lambasted Mamdani, calling him a "communist lunatic" and threatening to withhold funding from the city. Mamdani — who will be New York's first Muslim and South Asian mayor when he takes office Jan. 1 — campaigned on making the global business hub more affordable by using higher taxes on the wealthy to pay for free buses and city-run grocery stores, overcoming many voters' concerns about his pro-Palestinian views. Bloomberg Daybreak Editor Marc Perrier Joined Stephen Carroll and Caroline Hepker to discuss.
