When Trump was asked about whether his building sustained any damage in the September 11 attacks, he bragged about its size saying, “I mean, 40 Wall Street actually was the second-tallest building in downtown Manhattan, and it was actually before the World Trade Center the tallest, and then when they built the World Trade Center it became known as the second-tallest, and now it’s the tallest.” His building was still not the tallest.

Trump also claimed that he predicted the 9/11 attacks, and tweeted about “haters and losers” on its anniversary.
