Bill and Hillary Clinton to Become Grandparents Again

Chelsea Clinton announced Monday that she is expecting a second child next summer.

“Charlotte is going to be a big sister! Feeling very blessed & grateful this holiday season,” wrote Clinton on Twitter Monday.

Chelsea Clinton, 35, and her father, former President Bill Clinton, have largely stayed off the campaign trail since Hillary Clinton launched her Democratic primary bid in April.

Both have said they plan to intensify their public political roles after the New Year in an effort to boost Clinton’s campaign just six weeks before the first round of primary voting.
