As his very first mayoral function, following his midnight official swearing in ceremony held in the old, abandoned City Hall subway station, New York City Mayor Zohran Mamdani announced the appointment of Mike Flynn, described as a transportation leader, as commissioner of NYC Department of Transportation (DOT). The Mamdani administration said the appointment underscores its commitment “to delivering an affordability agenda through safer streets, faster buses, and transportation systems that work for working New Yorkers.”
