The Clintons have introduced their dynasty's newest addition to the world in a set of touching photos posted to social media.
Chelsea Clinton gave birth to Aidan Clinton Mezvinsky on Saturday, her second child with investment banker Marc Mezvinsky.
On Sunday, presidential hopeful and grandmother for the second time, Hillary Clinton, shared photos of their new bundle of joy on social media.
"What a joy being with our new grandson, Aidan. So grateful," Mrs. Clinton wrote on Twitter along with a photo of her and President Bill Clinton holding little Aidan.
Mr. Clinton also shared a photo of Aidan.
"Aidan has made two dads very happy this Father's Day. Hillary and I are thrilled for Marc and Chelsea!" the former president wrote with a photo of him and Mezvinsky holding the baby.
A third photo shows the proud parents with their new boy. "At 7:41 AM Saturday, our family and hearts expanded with Aidan’s arrival. We are blessed," Chelsea Clinton wrote.
Aidan was born at Lenox Hill Hospital in Manhattan, where his sister Charlotte, now 20 months old, was born in 2014.
