Former Mayor Rudy Giuliani, 9/11 families and first responders gathered at City Hall to demand Mamdani skip the event. They cited a petition with 101,000 signatures per Fox News and nearly 100,000 per ABC News. Neither outlet says who organized it or where the signers live. Gov. Kathy Hochul (Gov-D New York) said Mamdani should be there.

Medium
One speaker said Mamdani should 'do not show his face at that sacred ground'
Direct quote attributed only to an unnamed speaker at the City Hall event, traceable to the Fox News/The Hill account of the news conference.
Low
Mamdani is the first Muslim mayor to attend the 9/11 ceremony
Sweeping first-ever claim with no source in the story or sources list establishing it; the desk's own assertion.
Medium
Objections center partly on Mamdani's pick of Ramzi Kassem as chief legal counsel, who once represented a convicted al Qaeda member
Kassem's appointment is confirmed by CUNY Law, but the al Qaeda representation link rests on advocacy and opinion sources (Catholic League PDF, Washington Examiner) rather than a neutral news account.
