President Joe Biden and Vice President Kamala Harris were at Arlington National Cemetery on Wednesday afternoon.
The two were joined by the Obamas, the Bushes and the Clintons to lay a wreath at the Tomb of the Unknown Soldier.
President Donald Trump and first lady Melania Trump will not attend Biden’s inauguration, instead traveling to Florida. Trump’s refusal marks only the fourth time in history an outgoing U.S. president has not attended the next leader’s swearing-in ceremony.
