Trump has given multiple accounts of what he did on 9/11. In this account, Trump makes it sound like he personally went down to Ground Zero and pulled people from the rubble of the Trade Towers. There is no evidence for this.
In actuality, Trump called into UPN 9 (a local NYC channel at the time) and bragged that his building was now the tallest in the financial district because of the destruction of the Twin Towers. On UPN 9, he never mentioned that he "saw" Muslims celebrating the attack or that he was personally at Ground Zero to find survivors.
While running for President, President Donald Trump claimed that he helped rescue people from the rubble of the Twin Towers on 9/11. There is absolutely no proof that he did this.
Trump also claimed that on 9/11, he saw Syrian Muslims in Jersey City, New Jersey celebrating the destruction of the twin towers on the same.
On the day of the terrorist attacks, Trump called into UPN 9 and failed to mention either incidents (both 1 and 2), which had they happened, would have been beyond extraordinary.
