PITTSBURGH (KDKA) – Former President Donald Trump is coming to the Flight 93 National Memorial in Shanksville, Pennsylvania, on Wednesday to commemorate the Sept. 11 terrorist attacks, according to KDKA-TV political editor Jon Delano.

President Biden and Vice President Kamala Harris also plan a visit to the Flight 93 National Memorial on Wednesday. It is not yet known when Biden, Harris or Trump will visit. The White House said Biden and Harris would also travel to Ground Zero and the Pentagon.

The Flight 93 National Memorial in rural Somerset County, about an hour and a half from Pittsburgh, marks the spot where United Airlines Flight 93 crashed after passengers and crew decided to fight back against the hijackers. It is believed that the terrorists’ intended target was most likely the U.S. Capitol.

“Due to the quick and decisive actions of the passengers and crew, Flight 93 was the only one of the four hijacked aircraft that failed to reach the terrorists’ intended target that day,” the National Park Service explains on its website.

“The passengers and crew demonstrated unity, courage and defiance in the face of adversity. Today, the National Park Service, volunteers and partners are working to honor their actions and fully understand the legacy of Flight 93 and the events of September 11, 2001.”

Politicians often visit the memorial to commemorate the September 11 attacks. Last year, Second Gentleman Douglas Emhoff took part in a wreath-laying ceremony and in 2020 both then-President Trump and Biden came by to show their respect.
