Both President Donald Trump and Democratic challenger Joe Biden will commemorate the 19th anniversary of the Sept. 11 attacks in rural Pennsylvania where one of the hijacked planes crashed in a field, the White House and Biden’s campaign announced Wednesday.

It was not immediately clear whether their visits to the memorial in Shanksville will overlap. But it probably will be the closest that the candidates have been to one another in months.

The National Park Service, which co-hosts the annual memorial event, is planning an abbreviated ceremony this year to minimize the spread of the coronavirus. The agency plans a 20-minute “Moment of Remembrance” set to begin at 9:45 a.m., without a keynote speaker or musical guests. The name of each passengers and crew member from Flight 93 will be read aloud with the ringing of the “Bells of Remembrance,” according to the agency’s website.
