Bill and Hillary Clinton have reached many accomplishments, acquiring several coveted titles between them -- from Secretary of State to Commander-in-Chief -- but there's one title that still seems to evade them -- grandparent.
In an interview with ET's Nancy O'Dell, Chelsea Clinton, 33, revealed her parents' "unapologetic" pleads for her to have kids.
"There are not shy about saying that in public and private," said Chelsea, who wed investment banker Marc Mezvinsky in 2010.
Chelsea sat down with Nancy at the 9th Annual Clinton Global Initiative
, where she helped raise $80 million to curb the poaching and trafficking of the African elephant.
"I don't want the children I hope to have with my husband to grow up in a world without elephants," said Chelsea.
Since 2005, the Clinton Global Initiative
has been bringing together corporate and social leaders to implement innovative solutions to the world's most pressing challenges.
