NEW YORK (AP) — Presidential hopeful Hillary Clinton is a grandmother twice over.
Chelsea Clinton announced on Twitter Saturday that she has given birth to her second child, son Aidan.
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-year-old daughter named Charlotte.
Mezvinsky is the son of former U.S. Rep. Edward Mezvinsky and former U.S. Rep. Marjorie Margolies-Mezvinsky.
In a statement, Aidan's grandparents say they are overjoyed and "grateful for our many blessings."
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.
