The central disagreement over Mayor Zohran Mamdani's attendance is whether being at the 9/11 ceremony is a duty of the mayor's office or something victims' families can ask an official to forgo

Marking twenty-five years since the attacks that killed 2,977 people, the ceremony has become contested. A petition led by a victim's widower asks organizers to bar Mayor Zohran Mamdani, who intends to attend and has designated the date a citywide day of remembrance and service.
