There likely will be one more Clinton on the campaign trail next fall.
Chelsea Clinton, the only child of former President Bill Clinton and former Secretary of State Hillary Clinton, announced Monday that she is expecting her second child next summer.
"Charlotte is going to be a big sister! Feeling very blessed & grateful this holiday season," Chelsea Clinton wrote on Twitter.
Chelsea Clinton, 35, and her father have largely stayed off the campaign trail since Hillary Clinton launched her Democratic bid for the presidency in April.
Bill Clinton added: "Christmas comes early! @HillaryClinton and I are thrilled for Chelsea, Marc and Charlotte's growing family in 2016!"
