Mitt Romney doubled down against same-sex marriage Saturday, using his commencement address at Liberty University to reaffirm his belief that marriage is between "one man and one woman."
The presumptive Republican presidential nominee told graduates of the Jerry Falwell-founded evangelical university "culture -- what you believe, what you value, how you live -- matters."
"As fundamental as these principles are, they may become topics of democratic debate from time to time," Romney said. "So it is today with the enduring institution of marriage. Marriage is a relationship between one man and one woman."
President Barack Obama came out in support of same-sex marriage earlier this week.
The statement was one of Romney's loudest applause lines during his keynote speech.
