President Biden laid a wreath at the Flight 93 National Memorial Saturday after spending the the morning at the Ground Zero ceremony marking the 20th anniversary of 9/11.
Biden did not speak during the stop in Shanksville, Pa., where the fourth plane crashed after the passengers and crew took on the hijackers once they learned what had happened in New York.
Earlier in the day, former President George W. Bush and Vice President Kamala Harris took part in the official 20th anniversary ceremony at the memorial.
Along the way, the president stopped at the Shanksville Volunteer Fire Department, whose members were the first to respond when Flight 93 hit the ground.
“These memorials are really important,” Biden said. “But they’re also incredibly difficult for the people affected by them, because it brings back the moment they got the phone call, it brings back the instant they got the news, no matter how years go by.”
