Trump was in his Trump Tower penthouse, 4 miles (6.5 kilometers) from the World Trade Center, during the 2001 attacks. He has a mixed history with Sept. 11, often using the terrorist strikes to praise the response of New Yorkers to the attack but also making unsubstantiated claims about what he did and saw that day. He has also accused fellow Republican George W. Bush, who was president on Sept. 11, of failing to keep Americans safe.
