A petition with over 100,000 signatures is calling for Mamdani to be excluded from memorial ceremonies. The petition is led by relatives of 9/11 victims, who cite Mamdani's past comments and ties as the reason for their demand.

Critics of Mamdani plan to take their demand to City Hall. Former official Giuliani has also spoken out, describing the situation as "offensive".

Further details about the petition and the controversy surrounding Mamdani's potential attendance at memorial events are available from the source. The petitioners and critics are urging Mamdani not to attend the memorial events, but the outcome of their efforts is not specified.
