In video released from President Biden's meeting with Pope Francis, Biden gifted the pontiff with a military coin and cracked some jokes.
The footage from Vatican Television showed Biden handing Pope Francis a special coin with a deep personal significance: it bore the insignia of the 261st Signal Brigade, the Delaware National Guard unit in which his late son Beau served as a captain.
"I know my son would want me to give it to you," Biden said. In 2015, the Pope privately counseled Biden and members of his family in the months following Beau Biden's death.
Biden said the coins are given to "warriors and leaders," and called Francis "the most significant warrior for peace I've ever met."
After, Biden joked the Pope would have to buy him a drink if he doesn't have the coin the next time they meet.
"On the back of it, I have the state of Delaware, the 261st Unit my son served with. The tradition is — and I'm only kidding about this — next time I see you [and] you don't have it, you have to buy the drinks," Biden said to the Pope through a translator.
The Pope laughed at Biden's joke.
"I’m the only Irishman you’ve ever met who’s never had a drink," Biden said, before the Pope quipped that "Irish people love whisky."
Then Biden, 78, joked about age with Francis, 84. Biden relayed a story about trailblazing Black baseball player Satchel Paige, and described his attitude toward aging: "How old would you be if you didn't know how old you were?"
"You're 65," he said. "I'm 60. God love you."
The Bidens also presented the Pope with other gifts, including an embroidered vestment used by the Society of Jesus in the US, according to CNN's Delia Gallagher.
The pontiff also shook hands with US officials.
The meeting between the President and the Pope lasted 90 minutes. It was the fourth time Biden met with him.
