911 Memorial Glade with People

FILE- In this May 30, 2019 file photo, people gather around stones that are part of a new 9/11 Memorial Glade on the grounds of the National September Memorial and Museum after the Glade's dedication ceremony in New York. Set in a glade of trees during the spring 2019, the granite slabs recognize an initially unseen toll of the 2001 terror attacks: firefighters, police and others who died or fell ill after exposure to toxins unleashed in the wreckage.
