Former President Barack Obama offered tacit approval of Mayor Zohran Mamdani‘s agenda over the weekend as the two men met for the first time at a Bronx child care center. 

After having a private conversation, the two men led a sing-along with children, performing the “Wheels on the Bus” at the Learning Through Play Pre-K Center in the South Bronx and reading the book Alone and Together. The connection between the two men, viewed as two of the Democratic Party’s most influential leaders, comes after the former president called Mamdani and offered to be a sounding board for him, according to the Associated Press. They spoke on the phone in November, days before Mamdani became the first Democratic socialist to sit in City Hall.
