The daughters of former Vice President Dick Cheney are again publicly clashing over the issue of gay marriage.
Liz Cheney is running for a Senate seat in conservative Wyoming. Her younger sister Mary is married to a woman.
The sisters' latest spat on the issue began this weekend.
Liz Cheney appeared on "Fox News Sunday" saying, "I love Mary very much. I love her family very much. This is just an issue in which we disagree."
Mary Cheney responded on Facebook writing "Liz – this isn't just an issue on which we disagree – you're just wrong – and on the wrong side of history."
