Potential 2016 Democratic presidential nominee Hillary Clinton is a staunch supporter of LGBT rights. But according to audio Tuncovered by the Washington Free Beacon, this may have not always been the case.

According to Mediaite, the Free Beacon reported audio that features Taylor Branch, a friend of Bill Clinton, who said the former First Lady had a "discomfort" when it came to LGBT rights during her Senate race in the late 90s.

Branch made the recordings from notes he made with the former president for an oral history project. (He did not record the actual interview.) One recording from 1999, when Hillary Clinton was running for Senate, found Branch recalling Bill Clinton saying, "I've had much more contact in my life with gay people than Hillary has" and that she's "a little put off" by LGBT rights.

Branch said Bill Clinton, who was president when both Don't Ask Don't Tell and the Defense of Marriage Act were enacted, said his wife "had a kind of conservative religious temperament, and was not likely comfortable around gay people who were kind of acting out."

Regardless of her alleged past views, the 2016 Democratic presidential hopeful is now in full support of LGBT rights and has been vocal about the issue for some time.
