On September 11, 19 years ago in the United States, the “911” terrorist attack that shocked the world occurred. US President Trump issued a statement on the 10th local time announcing that on September 11th as Patriots Day, the nation will be lowered to half mast in mourning. The Trumps and White House staff mourned the victims of “911” in the meeting room on Air Force One.
