Mamdani's First 100 Days in NYC

In an exclusive interview with NBC's Kristen Welker, Mamdani reiterated his commitment to socialist policies, including a new tax on second homes for the wealthy.

He defended his agenda against criticism of funding shortfalls, stating that he believes in socialism 'even more' than before his election.

The Mayor also met with former President Barack Obama at a Bronx childcare center, where the two led a sing-along for preschoolers.

Mamdani's early tenure has been marked by a focus on affordability and a surprising willingness to engage with the Trump administration on key city issues.
