Hillary Clinton will have the birth of her second grandchild to look forward to next year -- perhaps right around the time of her party's nominating convention.
Chelsea Clinton tweeted Monday that she's expecting a second child "next summer."
The Democratic National Convention is slated to be held in late July in Philadelphia.
Hillary Clinton quickly responded on social media after the announcement as well.
The Democratic frontrunner frequently discusses her granddaughter Charlotte, who was born in 2014, on the campaign trail.
Earlier this year, in a preview of one of her campaign messages, Clinton wrote in a new epilogue to her book that "becoming a grandmother has made me think deeply about the responsibility we all share as stewards of the world we inherit and will one day pass on."
""I'm more convinced than ever that our future in the 21st century depends on our ability to ensure that a child born in the hills of Appalachia or the Mississippi Delta or the Rio Grande Valley grows up with the same shot at success that Charlotte will."
