The 36-year-old daughter of former President Bill Clinton and current presumptive Democratic presidential nominee Hillary Clinton lives in New York.

She and her hedge fund manager husband Marc Mezvinsky have a 20-month-old daughter, Charlotte. Both Charlotte and Aidan were born at Manhattan's Lenox Hill Hospital.

Mezvinsky is the son of former U.S. Rep. Edward Mezvinsky and former U.S. Rep. Marjorie Margolies-Mezvinsky.

Marc and I are overwhelmed with gratitude and love as we celebrate the birth of our son, Aidan Clinton Mezvinsky.

On Twitter, Chelsea Clinton said the couple is "overwhelmed with gratitude and love."

Aidan is the second baby to be born to the child of a presidential candidate this year.

In March, presumptive Republican nominee Donald Trump's daughter Ivanka gave birth to her third child, son Theodore James.
