Sisters Liz Cheney and Mary Cheney appear to be openly feuding when it comes to the still hot-button issue of same sex marriage, with their parents – Dick and Lynne Cheney – issuing a statement to quell the public familial dispute.

Liz Cheney Issues Support For 'Traditional Marriage'

On Sunday, Liz Cheney, who is launching a bid to become the Republican Wyoming Senate candidate, appeared on Fox News Sunday where she was asked about her position on same-sex marriage. Her opinion on the matter is of particular interest in the political sphere, as sister Liz Cheney is a lesbian who is openly married to wife Heather Poe.

“I do believe in the traditional definition of marriage. I love Mary very much. I love her family very much,” Liz Cheney told host Chris Wallace. “This is just an issue on which we disagree.”

Mary Cheney, Heather Poe Respond To Liz Cheney

Following the interview, Poe took to Facebook to share her thinly veiled disgust with her sister-in-law. "Liz has been a guest in our home, has spent time and shared holidays with our children, and when Mary and I got married in 2012 — she didn't hesitate to tell us how happy she was for us," Poe wrote. "To have her now say she doesn't support our right to marry is offensive to say the least."

Mary Cheney shared her wife’s Facebook message on her own page, adding, “Liz — this isn’t just an issue on which we disagree — you’re just wrong — and on the wrong side of history.”

Cheney Parents Defend Liz Cheney

On Monday, former vice president Dick Cheney and his wife Lynne released a public statement supporting Liz’s claims that she supports traditional marriage – and only traditional marriage – while asserting that she is also a dutiful and kind sister. "She has also always treated her sister and her sister's family with love and respect, exactly as she should have done," the Cheneys said. "Compassion is called for, even when there is disagreement about such a fundamental matter, and Liz's many kindnesses shouldn't be used to distort her position."

"This is an issue we have dealt with privately for many years, and we are pained to see it become public," they added. "Since it has, one thing should be clear. Liz has always believed in the traditional definition of marriage."

Despite her parents’ public vouching for her stance in support of traditional marriage, Liz Cheney’s previous statements regarding same-sex marriage show she hasn’t always been so socially conservative on the issue. “My family's been very clear about this,” she started, when addressing a question regarding marriage equality in 2004 for MSNBC. “We think freedom means freedom for everybody.”
