Mayor-elect Zohran Mamdani named veteran budget hand Dean Fuleihan as first deputy mayor and tapped longtime aide Elle Bisgaard-Church as chief of staff, signaling a mix of youthful allies and seasoned operators. Announcing the picks at an Upper East Side mansion once used by Franklin D. Roosevelt, Mamdani said his team will be judged on big promises and basics like trash pickup. He faces steep hurdles to fund free buses, expanded child care, and a rent freeze, amid mixed signals from Gov. Kathy Hochul and threats from President Trump.
