Mayor Zohran Mamdani said he would attend the 25th anniversary 9/11 ceremony to honor victims' families and first responders, and attended it on September 11, 2026

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.
