Clinton and Mezvinsky, a hedge-fund executive, married in July 2010. Clinton announced she was pregnant on Twitter in January, sharing how thrilled she was for her children to become a big brother and sister.
She told PEOPLE in a September 2015 interview that becoming a parent changed her world and even enhanced her feelings for husband, explaining, “I didn’t know I could care more intensely about anything until I became a mom.”

Becoming a mom is also what initially sparked Clinton’s interest in becoming a children’s book author.
“[My kids] love being read to and talking about what they’re reading in books. Particularly for young readers, books are not only a way to help break down and communicate ideas [but] stories of real empowerment,” she told PEOPLE this past October.
Clinton’s latest children’s release, Don’t Let Them Disappear, discusses endangered animals and “provides helpful tips on what we all can do to help prevent these animals from disappearing from our world entirely,” according to the book’s description.
