Cheneys Welcome Seventh Grandchild

ABC News' Ann Compton and Nitya Venkataraman report:

Mary Cheney, former Vice President Dick Cheney’s lesbian daughter, had her second child this morning at Sibley Hospital in Washington, DC.

Sarah Lynne Cheney was born at 8:17 a.m., weighing 6lbs., 14 oz. Her parents are Mary and her partner of 18 years, Heather Poe. The couple’s first child, Samuel David Cheney, was born in May 2007.

The December 2006 announcement of Ms. Cheney’s first pregnancy garnered national headlines, and was marked by a notably terse exchange between the then-vice president and CNN’s Wolf Blitzer.

During a January 2007 appearance on CNN, Cheney bristled after Blitzer asked him to respond to a statement from ‘Focus on the Family’ about whether having a child outside of a married mother or father is best for the child.

Though Blitzer stood by his line of questioning, Cheney deemed it “out of line”.

The pregnancy also hit awkward notes for the Bush administration who won re-election in 2004 in no small part because of its opposition to gay and lesbian marriage.

In a 2004 interview with the New York Times, Bush said “studies have shown that the ideal is where a child is raised in a married family with a man and a woman."

Mary Cheney campaigned for the Bush-Cheney presidential campaign in both 2000 and 2004, though her position on that point was clearly divergent from the president’s.

In a 2005 interview, Ms. Cheney told Diane Sawyer, "Every study has confirmed what matters is that children are raised in a loving and supportive environment. And there's no reason why that can't be provided by a same-sex couple."
