Add another heir to the political dynasty.
Chelsea Clinton, daughter of former president Bill Clinton and presumptive Democratic nominee Hillary Rodham Clinton, announced on Saturday that she had given birth to a son. The child is her second with husband Marc Mezvinsky.
Chelsea made the announcement via Twitter, coincidentally just a day before Father's Day:
On Sunday, Clinton and her husband released a photo with the second time mother holding her newborn son.
The former (and perhaps future) first daughter has been an active campaigner for her mother, who has currently all but sown up the Democratic nomination.
In a joint statement, the grandparents described themselves as "overjoyed" and "over the moon" about Aidan's birth.
