There are over 101,000 signatures gathered in New York to have Mayor Mamdani not come to the 9/11 ceremony.

Key evidence

• The Guardian, ABC News and ABC7 New York reported a petition with nearly 100,000 or close to 100,000 signatures, while earlier USA Today reporting recorded more than 65,000 on August 1,
• The only supplied source reporting more than 101,000 calls the signers Americans, not New Yorkers, and does not provide independently verifiable petition data.
• The petition seeks to influence Mamdani’s attendance. It does not itself bar him from the ceremony, and reporting indicated that he planned to attend.

Detailed analysis

Multiple reports confirm that an online petition, launched by relatives of people killed in the September 11 attacks, sought to keep Mayor Zohran Mamdani from attending New York City’s 25th-anniversary remembrance ceremony. The reported total rose from more than 65,000 signatures on August 1 to more than 98,000 or nearly 100,000 in early September. (SOURCES_1, 3, 4, 6, 10) The specific figure of more than 101,000 appears in a September 8 report by CDM, which describes the signers as Americans, including 9/11 families. That wording does not establish that the signatures were gathered in New York, nor does it show that all or most signers were family members. The stronger and more established reporting in the supplied sources describes the total as close to or nearly 100,000, generally attributing the figure to supporters of the petition. (SOURCES_2, 4, 9) The petition reflects opposition to Mamdani’s attendance, not a binding decision preventing him from going. ABC News reported that Mamdani planned to attend, and the supplied coverage says he designated September 11 as a day of remembrance and service. The sources also document criticism from former Gov. George Pataki, former Mayor Rudy Giuliani and some 9/11 families, but those statements do not change the petition’s uncertain geographic composition or independently verify the exact count. (SOURCES_1, 2, 4, 7, 10) The claim therefore combines a broadly supported point, that a petition opposing Mamdani’s attendance had nearly 100,000 signatures, with a more specific figure and location that the available evidence does not substantiate. The evidence supports describing the petition as having roughly 100,000 signatures, but not confidently as more than 101,000 signatures gathered in New York.
