Zohran Mamdani attended the 9/11 remembrance ceremony in New York. Rudy Giuliani had said he ought not to attend. The brother of a Muslim police officer killed in the attacks said he was troubled by those calls. Mamdani was beside Representative Alexandria Ocasio-Cortez. He refused to remain absent.
Separately, his administration started a free childcare programme for two-year-olds. The rollout encountered high demand and glitches. Mamdani also commented on the city not sharing early information about toxic air after the 9/11 attacks.
