I am proud to announce $2 million for the @Sept11Memorial in NYC! This special site ensures that the memory of the nearly 3,000 people killed in the terror attacks of September 11, 2001, as well as those lost in the World Trade Center bombing in 1993, will never be forgotten!— Donald J. Trump (@realDonaldTrump) July 17, 2020
