As the 25th anniversary of the September 11 attacks nears, bereaved families say their grief remains unresolved, compounded by the long-delayed trial of the attack's alleged mastermind. Newly released documents cited by NYC mayoral candidate Zohran Mamdani reveal that toxic air lingered in New York for months after the attacks despite official assurances of safety, reigniting anger among survivors and families of first responders who developed illnesses. Separately, the Tunnels to Towers Foundation is touring the U.S. with a 21-foot steel beam salvaged from the World Trade Center's South Tower, aiming to educate younger Americans who have no personal memory of the attacks.
