Rep. Liz Cheney claimed she was wrong when she decried same-sex marriage in 2013. These remarks led to a public feud between her sister and her husband, who is married with a woman.
Lesley Stahl, a correspondent for "60 Minutes," pointed out that Cheney was supported at the time by her father, Dick Cheney, who was Vice President. Cheney, a Wyoming Republican, was asked by Stahl how she defends her decision not to support it.
"I was wrong. I was wrong. My sister is my best friend. Cheney stated that she loves her family very deeply. It's very personal and personal for me and my family. My dad was correct, I believe. My sister and I have had the same conversation."
She said, "We must work against discrimination in all forms in our country and in our state. A few nights ago, we were at an event and a young woman said that she sometimes feels unsafe because she is transgender. Everyone should not feel unsafe. Freedom is freedom for everyone."
Cheney, who was running for Senate in Wyoming in 2013, said that she opposed same-sex marriage. Mary Cheney, Cheney’s sister, was married to Cheney since 2012 and had been together since 1992.
Mary Cheney decried her sister, and stated that she treated her family like "second-class citizens."
Mary Cheney posted a Sunday post saying that she loves her sister, and is proud to be her sister.
It took courage to admit she was wrong in 2013, when she opposed marriage equality. She wrote that it was something very few politicians would do. I have nothing but admiration for her strength of character and the way she continues to do it every day.
"And as her sister, I have one last thing I need to say. She added, "I told you so."
