Biden and Harris appear together for the first time since she lost the election to Trump

WASHINGTON â€”  President Biden and Vice President Kamala Harris on Monday made their first joint appearance since her election loss when they observed Veterans Day together by laying a wreath at the Tomb of the Unknown Soldier at Arlington National Cemetery.

Biden honored the service and sacrifice of America’s military veterans, including those who paid the ultimate price, and their families, during his final time speaking at the cemetery’s memorial amphitheater in his capacity as commander in chief of the U.S. military.

“It’s been the greatest honor of my life to lead you, to serve you, to care for you, to defend you, just as you defended us, generation after generation after generation,� Biden said. “You are the greatest fighting force, and this is not hyperbole, the finest fighting force in the history of the world.�

He reminisced about trips to U.S. military installations around the world, and to such historic military sites as Valley Forge and Gettysburg in Pennsylvania.

Biden also announced that the Department of Veterans Affairs is expanding the types of cancers covered under the PACT Act, legislation he signed to expand healthcare services for veterans who served at military bases where toxic smoke billowed from “burn pits.�

Over 1 million veterans and families have already been helped under the law, he said.

The president opened his brief remarks by stating that America’s “truly sacred obligation� is to prepare those it sends into harm’s way and care for them when they come home, or don’t.

“To all the military families, to all those with a loved one still missing or unaccounted for, to all Americans grieving the loss of a loved one who wore the uniform, Jill and I want you to know we see you, we thank you and we’ll never stop working to meet our sacred obligation to you and your family,� he said.

Biden’s son Beau served in the Delaware Army National Guard and deployed to Iraq in 2008 for about a year. He died of brain cancer in 2015 at the age of 46.

Biden and Harris, accompanied by Veterans Affairs Secretary Denis McDonough, wore solemn expressions as they approached the tomb. They placed their hands over their hearts as the national anthem played before the wreath-laying, and again afterward as taps sounded.

The president and First Lady Jill Biden had hosted veterans and members of the military community at the White House before they and Harris and her husband, Doug Emhoff, departed for the burial ground on the other side of the Potomac River from Washington.

It was the first time that Biden and Harris had been seen together in public since the vice president lost last week’s election to former President Trump.

After the observance, Biden was traveling home to Wilmington, Del., for reasons the White House had yet to disclose.
