WATCH: Biden observes 9/11 anniversary at Flight 93 memorial in Shanksville

Former Vice President Joe Biden laid a wreath under First Officer LeRoy Homer’s name at the Flight 93 memorial in Shanksville, Pennsylvania, before going to greet some of Homer’s family members with elbow bumps.

Biden then went on to greet another family of a Flight 93 victim, as well as a young bagpipe player, whom he asked about her college plans.

He spoke to a few people gathered about his respect for the passengers on the flight that sacrificed themselves to help bring it down, and said sacrifices like theirs “mark the character of a country.”

President Donald Trump delivered a speech at a commemoration event in Shanksville earlier Friday.

This was the second memorial visit for Biden Friday.

He also attended the ceremony at ground zero in New York, exchanging an elbow bump with Vice President Mike Pence before the observance began.
