Former presidents join Biden.

In one of his first acts as president, buttressed by several of his predecessors, President Joe Biden on Wednesday moved a ceremonial segment of his inauguration to Arlington National Cemetery in Virginia, paying his respects at the Tomb of the Unknown Soldier.

Reflecting upon the memorial on the first sunny Inauguration Day in 28 years, former Presidents Barack Obama, George W. Bush and Bill Clinton stood by as Biden arrived with Vice President Kamala Harris to lay a wreath before the tomb, standing in silence for a long moment in a solemn display of solidarity.

Approaching the wreath, Biden made the sign of the cross before saluting while a military band’s trumpeter played taps.

Biden never served in the military, having received draft deferments during the Vietnam War. But his display honored current and former members of the military even as it called to mind his son Joseph R. Biden III, known as Beau, who served as an Army major and died of brain cancer in 2015.

The choice to visit the tomb immediately after the inauguration was a first for a newly elected president, providing a bipartisan display of support for the country’s armed forces.

Former first ladies Michelle Obama, Laura Bush and Hillary Clinton stood by in silence as the ceremony took place.

Former President Jimmy Carter was unable to attend the inauguration.
