Zohran Mamdani: Now, close to 25 years later, more people have died from 9/11-related illnesses than were killed on the day itself. It would be one thing if government had stood alongside survivors and provided them with everything they needed at every step of the way. And yet, we know that could not be further from what actually happened. People got sick because the leaders they trusted lied and told them they were safe to breathe in toxic air. And then when they began to contend with the symptoms of the illnesses that followed, the government that had not hesitated to send them into harm’s way was nowhere to be found.
