NEW YORK — Mayor Zohran Mamdani said Sunday he’ll move ahead with plans to open five city-run grocery stores, with the first set to debut next year in East Harlem.

Mamdani, a democratic socialist who took office in January, made the pledge during a speech to celebrate his first 100 days in office. During his remarks, Mamdani leaned heavily into a philosophy that has made him one of the preeminent leaders of the nation’s political left wing.
