The president spoke at a ceremony in Pennsylvania at the site of the Flight 93 crash while Biden attended a New York memorial
Donald Trump and his election rival Joe Biden struck a temporary ceasefire but avoided crossing paths on Friday as they joined millions of Americans in commemorating the 19th anniversary of the September 11 terrorist attacks that killed a total of almost 3,000 people in New York, Washington and Pennsylvania.
This year the rituals of remembrance were different and the tragedy was marked as another continues to unfold: the coronavirus pandemic has cost 191,000 American lives – the equivalent of a 9/11 for 64 consecutive days.
