President Biden and Vice President Harris will mark the 23rd anniversary of the Sept. 11 terrorists attacks in New York, Shanksville, Pa., and at the Pentagon, the White House confirmed Wednesday.

“You will see the president and vice president next week together as they mourn the thousands of lives that were lost on that day and also the first responders who obviously put their lives on the line to protect Americans on that day,” press secretary Karine Jean-Pierre told reporters.

Biden and Harris will travel to Ground Zero in New York, then to the Flight 93 Memorial in Shanksville, and then to the Pentagon in Arlington, Va., to mourn the victims of the attacks at all three sites.

The Trump campaign did not respond to a request for comment on his plans for the anniversary. The New York Times reported the former president is considering a visit to the World Trade Center site, also known as Ground Zero.

Harris visited the 9/11 memorial in lower Manhattan on last year's anniversary while Biden marked the anniversary in Alaska, which garnered criticism. He had been returning from an overseas trip to Asia when the anniversary occurred.

First lady Jill Biden had laid a wreath at the Pentagon Memorial last year, which honors those killed. Hijackers flew planes into the Pentagon and both World Trade Center towers with a fourth plane crashing into a field in Pennsylvania.

Harris will travel to New York City next Wednesday following a trip to Philadelphia the day before for a presidential debate against former President Trump.
