A petition opposing New York City Mayor Zohran Mamdani's 9/11 ceremony attendance reached about 110,000 signatures by September 10, 2026, citing his appointment of lawyer Ramzi Kassem as chief counsel

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.
