Obama and Mamdani meet in Bronx

The meeting comes as Mamdani, a democratic socialist, completes his first 100 days in office and seeks to build national alliances.

Obama and Mamdani read 'The Wheels on the Bus' to a group of students, emphasizing the importance of early childhood education and community support.

The visit also served as a platform for Mamdani to discuss his proposed 'pied-à-terre tax' on luxury second homes, which has drawn both support and controversy.

The high-profile appearance with the former president is seen as a major endorsement of Mamdani's leadership and progressive agenda.
