“Let's say you're on the campaign trail ... and a supporter approaches you and says, 'Senator, I'm old fashioned, and my faith teaches me that marriage is between one man and one woman,' what is your response?” Morgan Cox, chairman of the HRC's board of directors, asked Warren.

"Well, I'm going to assume it's a guy who said that," Warren began, to laughter. "And I'm gonna say, 'Then just marry one woman. I'm cool with that.'"

After waiting for initial applause to die down, Warren interjected again: "Assuming you can find one."
