Chelsea Clinton gave birth to a boy, her second child, Saturday morning.
The only daughter of the presumptive Democratic presidential nominee announced the birth on Twitter just before noon.
Marc and I are overwhelmed with gratitude and love as we celebrate the birth of our son, Aidan Clinton Mezvinsky.

Clinton, 36, has been married to Marc Mezvinsky since 2010. The couple has a 2-year-old daughter, Charlotte.
“We are overjoyed to be grandparents again with the arrival of our grandson,” Bill and Hillary Clinton said in a statement.
“We are all over the moon as Chelsea and Marc welcome Charlotte’s little brother to the world and grateful for our many blessings. Chelsea and Aidan are both doing well and enjoying this very special time together.”
Aidan’s arrival comes two days after Grandma Clinton’s campaign began a $7.3 million ad blitz in swing states that pushes her as a motherly figure whose career has focused on children.
