U.S. President Joe Biden and Vice-President Kamala Harris on Monday made their first joint appearance since her U.S. selection loss when they observed Veterans Day together by laying a wreath at the Tomb of the Unknown Soldier.

The pair then headed to the ceremonial amphitheater at Arlington National Cemetery, where Biden honored the service and sacrifice of America's military veterans — including those who paid the ultimate price, and their families — during what was his final time speaking there as as commander in chief of the U.S. military.

“It's been the greatest honour 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 health care services for veterans who served at military bases where toxic smoke billowed from “burn pits."

Over 1 million veterans and families have 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.
