Joe Biden and wife Jill Biden acknowledged the birth of their new grandchildren more than a week after the latest addition to the family of the presumptive Democratic presidential nominee.

"We have three children, and we have six grandchildren," Jill Biden said at the beginning of a virtual town hall Sunday night.

The two-term vice president added, during the online event dedicated to helping families adjust to life amid the coronavirus pandemic, that their grandchildren ranged from "seniors in law school to little infants."

Joe Biden's second son, Hunter Biden, 50, and his second wife, Melissa Cohen, 33, welcomed a baby boy on March 28, according to the New York Post. But during an appearance last week on NBC's The Tonight Show Starring Jimmy Fallon, Joe Biden, a Delaware senator for 36 years, failed to mention the newborn.

"I have five grandchildren. Every single day, I either talk to them or we text,” Biden told Fallon.

That accounting from Delaware's 36-year senator also omits Hunter Biden's daughter with Lunden Roberts, a 29-year-old Arkansas woman who gave birth in August 2018. Biden originally denied he was the father of Roberts's baby but agreed in March to provide child support payments after a paternity battle.

Hunter Biden has three older children with his first wife, Kathleen Buhle, his partner of 24 years. The couple separated in 2015 and divorced in 2017. Biden married Cohen, a South African filmmaker, last May after meeting her a week earlier.

Joe Biden has another two grandchildren through his deceased son Beau and his widow Hallie Olivere. Joe Biden's daughter Ashley married Howard Krein in 2012, but the pair don't have any children.
