The feud between Mary and Liz Cheney has ramped up with Mary Cheney taking to Facebook to accuse her sister of regarding Mary and her wife as "second class citizens."
"This isn't like a disagreement over grazing fees or what to do about Iran," Mary Cheney wrote to a commenter on her Facebook page who suggested she should be "lovingly tolerant" of her sister's position. "There isn't a lot of gray here. Either You think all families should be treated equally or you don't. Liz's position is to treat my family as second class citizens. That's not a position I can be 'lovingly tolerant' towards."
