Mary Cheney Pregnant With Second Child

Sources say that Mary Cheney, the lesbian daughter of former vice president Dick Cheney, is pregnant with her second child.

The staunch Republican and her partner, Heather Poe, expect the baby in mid to late November, according to True/Slant, which spoke with a source close to the Cheney family.

"Cheney has worked as a principal at Navigators Global, a bipartisan communications firm, but recently announced that she would be leaving the company for maternity leave and to begin a new consulting firm with her sister, Liz. Close friends were informed that she was expecting a second child about four months ago and she is now visibly showing her pregnancy, the source says," according to True/Slant.

Cheney, 40, gave birth to her first child, Samuel David Cheney, in May 2007. She and Poe live in Virginia.
