Naomi Biden, Granddaughter of Joe Biden, Marries Peter Neal in White House Wedding That's a Historic First

Naomi Biden and Peter Neal tied the knot Saturday morning in a long-anticipated White House wedding, the first in nearly a decade — and the first-ever for a grandchild of a sitting president.

The couple were wed in a private ceremony on the South Lawn, attended by Naomi's grandparents, President Joe Biden and first lady Jill Biden.

Naomi Biden was walked down the aisle by both her father and her mother, a source close to the family tells PEOPLE. Also, in another sentimental nod to Naomi's closeness with her mother, the bride carried Lilies of the Valley, a tradition in her mother's family.

The all-day celebration will continue with a White House luncheon for the wedding party and close family members, followed by an evening reception at the executive mansion with dessert and dancing.

Naomi, 28, is a graduate of Columbia Law and the eldest daughter of the president's son Hunter Biden and Hunter's ex-wife, Kathleen Buhle.

Neal, 25, who also studied law, interned for Hillary Clinton's presidential campaign and at the White House during Barack Obama's presidency.

According to two sources, Naomi and Neal currently live on the third floor of the White House residence — one flight up from the First Family's main living quarters — and the same place Michelle Obama's mother, Marian Robinson, called home for the eight years of her son-in-law's administration.

The pair announced their engagement in September 2021, and confirmed earlier this year that they had chosen the White House as their venue. Their nuptials marked the first wedding on the White House grounds since 2013, when presidential photographer Pete Souza married Patti Lease in the Rose Garden.

Naomi has two sisters, Finnegan and Maisy, as well as two young half-siblings, including a boy born in March 2020 named Beau, after her uncle, Beau Biden, who died of brain cancer in 2015 at 46.

President Biden, who turns 80 on Sunday, has talked at length about the close bond he and each of his grandchildren share. Just before Biden was inaugurated, Naomi, who also lives in Washington, D.C., told Today's Jenna Bush Hager that she was excited to know her "Pop" would live only a few miles away.

In a past interview with PBS Newshour, Naomi explained that her grandfather is at the center of the close-knit Biden clan.

"We've grown up together," she said. "He's made sure that every single tradition, every holiday, we're all together . . . I don't think there's been any decision, no matter how big or small, that we haven't decided as a family."
