Around the country, some communities canceled 9/11 ceremonies, while others went ahead, sometimes with modifications. "We took all our advertising down, it's a solemn day, and that's how we're going to keep it, OK?"
"First for me: Trump campaign tracked me down from pics I tweeted and escorted me out", she said. Chuck Schumer, D-N.Y., right, and New York Gov. Andrew Cuomo, at the National September 11 Memorial in New York, Friday, Sept. 11, 2020, before a ceremony marking the 19th anniversary of the Sept. 11 terrorist attacks.
Stephen Clark, superintendent of the Flight 93 National Memorial, said the passengers on Flight 93 were strangers who "came together in this national moment of uncertainty".
The virus also altered the memorial event, with family remembers pre-recording the traditional reading of the names of the victims and the crowds at the site severely restricted.
Democratic presidential candidate Joe Biden and Vice President Mike Pence, both masked, joined New York's somber 19th anniversary of the September 11 attacks, while President Donald Trump marked it at the Pennsylvania crash site of a hijacked jet.
Trump began the day in Shanksville, Pennsylvania, where passengers crashed a hijacked plane believed to have been headed to the U.S. Capitol or White House.
In his remarks, he mentioned the death of Qasem Soleimani and Abu Bakr al-Baghdadi, but not Osama Bin Laden, the mastermind of the 9/11 attacks, who was killed in an operation overseen by his predecessor, President Obama.
During a virtual fundraiser on Thursday, Biden - who the president often refers to as "Sleepy Joe" - said he looks forward to holding Trump accountable on the debate stage.
Vice President Pence and Biden, the Democratic presidential nominee, both attended a memorial service Friday morning at the site of the World Trade Center, whose twin towers were destroyed in the attack.
He also honoured first responders as well as military personnel who fought to "preserve our freedom" in the subsequent wars launched under former President George W. Bush.
During yesterday's NY ceremony he stood just a few feet from Vice President Mike Pence, with whom he chatted and shared an elbow bump, and Governor Andrew Cuomo.
In a Saginaw County airplane hangar with Air Force One as his presidential backdrop and all the usual "Make America Great Again" trappings, Trump excoriated his rival for more than an hour, lingering on the former DE senator's support for the original - and much-hated - North American Free Trade Agreement.
Biden also traveled to Shanksville but there was no chance of the rivals crossing paths, as Trump left well before the Democratic candidate and his wife Jill arrived.
Biden offered condolences to a woman he spotted crying in the crowd of hundreds, Amanda Barreto, who lost her aunt and godmother in the attacks. He told her he lost his son as well, and lamented, "It never goes away, does it?"
Mr Trump did not attend the ceremony in his home city, sending Mike Pence instead. She told Biden he had died in his early 40s. "I understand there's all this, and I understand now that we have even COVID", said Cho, 55.
