Biden laid a wreath of white flowers at the Shanksville, Pennsylvania, memorial marking the names of passengers and crew who died when hijacked Flight 93 crashed on September 11, 2001.

He met with three families and, joined by his wife, spoke about his own losses, though most of his private comments were not audible to media travelling with the candidate. The grief of losing a loved one to tragedy “never goes away”, he said.

A couple hundred spectators ringed the memorial and stood on the grass. There were a number of news reporters that stayed over from President Trump’s earlier visit. Before leaving the memorial site, Biden answered questions from the public about September 11.

14:10 ET – Trump threatens to put down any election night riots: TV interview

President Trump told Fox News host Jeanine Pirro in a taped television interview set to air on Saturday night that he would direct federal law enforcement to “very quickly” put down protests in the streets should he win re-election.

“We’ll put them down very quickly if they do that,” Trump said in an advance audio clip of the interview aired on the show Fox and Friends.

“We have the right to do that. We have the power to do that if we want. Look, it’s called ‘insurrection’. We just send in and we do it very easy. I mean, it’s very easy. I’d rather not do that because there’s no reason for it. But if we had to do that, we’d put it down within minutes – within minutes,” Trump told Pirro.

Joe Biden visited the Flight 93 memorial park in Shanksville, Pennsylvania, to honour the lives of 33 passengers and seven crew members who died in the plane crash. At an earlier ceremony in New York City, Biden commented on the depth of grief and pain family members and survivors feel.

“It takes a lot of courage for someone that lost someone to come back today,” Biden told an Associated Press reporter travelling with him.

“I know from experience, losing my wife, my daughter, my son, you relive it, the moment as if it’s happening. It’s hard. It’s a wonderful memorial, but it’s hard. It just brings you back to the moment it happened, no matter how long, how much time passes. So I admire the families who come.”

08:10 ET – Joe Biden has landed at Newark Liberty Airport en route to Ground Zero

Before leaving for New York, Biden said he did not plan to make news, or hold any press conferences calling it “a solemn day”.

“I’m not going to talk about anything other than 9/11. We took all our advertising down. It’s a solemn day. That’s how we’re going to keep it.”

The 9/11 commemoration ceremony Biden and his wife will attend will be different from previous years with the names of those killed not being read out live, but pre-recorded because of coronavirus restrictions.

Participants are required to wear face coverings and practice social distancing on the Memorial plaza where the World Trade Center towers once stood.
