The question came up again at a Politico event featuring former Vice President Dick Cheney, Liz Cheney, and Lynne Cheney on Monday.
Questions on the topic have been particularly important to the Cheneys as Mary, one of the vice president's daughters, is a lesbian who is married to Heather Poe. Liz Cheney, the former candidate for U.S. Senate in Wyoming, has repeatedly said she opposes same-sex marriage. Mary has said she's "dead wrong" on the issue.
"I love Mary very much and Heather and the kids and I don't have anything new to add about that," Liz Cheney said at the event.
Moderator Mike Allen then tried to press Liz Cheney, but she wouldn't budge.
"I'm not going to add anything to the issue," Cheney said.
Allen then asked Lynne Cheney if she thought the disagreement had gotten out of hand.
"I think the best thing about being a mom is having terrific children — which I do— and wonderful grand children — which I do — and if I were those children or those grandchildren the last thing I would want is my mother in a public forum commenting on personal disputes in my family so that's it," Lynne Cheney said.
