WATCH: Biden and Harris families lay wreath at Arlington National Cemetery

President Joe Biden spent a few of the first moments of his term at Arlington National Cemetery, honoring fallen veterans with three former presidents and their families.

Watch the event in the player above.

The president, first lady Jill Biden, and newly sworn-in Vice President Kamala Harris and her husband, Doug Emhoff, presided over a wreath-laying ceremony at the Tomb of the Unknown Solider on Wednesday.

After cannon fire rumbled in the distance, Biden saluted as a military band played the national anthem.

Biden and Harris later briefly touched the wreath before bowing their heads in prayer. The president also made the sign of the cross, then he and Harris stood somberly for the playing of taps.

Joining them at the ceremony were former President Barack Obama and his wife, Michelle, former President George W. Bush and his wife, Laura and former President Bill Clinton and his wife, Hillary.

Former President Donald Trump flew to Florida before Biden was sworn into office.
