Zohran Mamdani going to the 9/11 Memorial Ceremony on Friday will be the single most disrespectful act to the families of the victims of that day. He handed a ceremonial pen to Ramzi Kassem — his chief counsel, the lawyer who represented an Al-Qaeda terrorist whose sister was married to one of the Pentagon hijackers. He didn’t give it to a firefighter’s widow. He didn’t give it to an FDNY chief. He didn’t give it to a victim’s family member. Now he wants to stand at Ground Zero on Friday like he belongs there. The families have asked him not to come. Giuliani told him not to come. A 100,000 people signed a petition telling him not to come. Ground Zero is a sacred place, not a photo-op for a mayor who just handed a 9/11 souvenir to an Al-Qaeda defense lawyer. Stay away. Your presence is a slap in the face to every family still burying pieces of their loved ones 25 years later. Never forget.
