Cardi B is all in when it comes to backing New York City Mayor Zohran Mamdani's new 2-K program. Source: Kevin Wong / Anadolu On Friday, April 3, Cardi teamed up with the mayor to roll out a citywide contest to get families excited about the program. The goal for this initiative is simple: find the perfect jingle to spread the word about free childcare. Mamdani and his administration is asking people to submit original 15- and 30-second songs, with Cardi helping narrow things down before New Yorkers vote on the final winner.
