NBC News confirmed that the boy's name is Beau, in honor of Hunter's late brother and Joe's eldest son, Joseph Robinette "Beau" Biden III, the former attorney general of Delaware who died at 46 in 2015 of brain cancer.

The little boy was also held by his father in the crowd as his grandfather was being sworn in as president at the U.S. Capitol.

The president was then pictured sharing a touching moment with his grandson at the White House, holding him and giving him a kiss after a full day of inauguration ceremonies.

Hunter Biden also has three children with his first wife, Kathleen Buhle. His daughters Naomi, 27, Finnegan, 22, and Maisy, 20, and Beau's daughter, Natalie, 16, all spoke with TODAY's Jenna Bush Hager about their close bond with their grandfather and what it was like finding out he had won the election.

"It's like your whole body, I mean everyone was crying, it was just like, we embraced each other and I think we'll always remember that moment," Finnegan said.

A day before the inauguration, Biden honored his late son with a speech at the Major Joseph R. "Beau" Biden III National Guard/Reserve Center in the Bidens' home state of Delaware.

"I am even more proud to be standing here doing this from the Major Beau Biden facility. Ladies and gentlemen, I only have one regret: He's not here," Biden said tearfully. "Because we should be introducing him as president."

Biden also visited Beau's grave on Election Day ahead of the biggest day of his life. Beau was also honored during the inauguration when Hunter, Biden's daughter Ashley, and Biden's grandchildren entered the inaugural ceremonies as the Marine Corps Band played John Philip Sousa’s "Beau Ideal."
