Their daughter, Chelsea, announced the baby’s delivery via her twitter handle and on facebook. She said: “Marc and I are full of love, awe and gratitude as we celebrate the birth of our daughter, Charlotte Clinton Mezvinsky,” Hillary, a former senator and immediate secretary of state, recently prospected being titled a grandmother, describing it her “most exciting title yet.” She was also reported to have picked the classic Goodnight Moon as the first book she would read to her grandchild. Clinton, 34, wedded her teenage friend Marc Mezvinsky in 2010. She was educated at the Stanford and Columbia universities and, earned a doctorate from Oxford University.
