Mitt Romney's opposition to gay marriage is highlighted in a video released Thursday by the National Organization for Marriage (NOM).

The video mashes together some of Romney's most memorable moments speaking out against marriage equality.

“When I ran for governor, one of the big issues was marriage, gay marriage. My opponent said she'd sign a bill in favor of gay marriage. I said I would not; that I oppose same-sex marriage. At the same time, I would advance, if you will, the efforts not to discriminate against people who are gay,” Romney said in an appearance on CNN's Piers Morgan Tonight.

In an address to the NAACP, Romney said that as president he would represent “all Americans, of every race, creed and sexual orientation,” then added that he would “defend traditional marriage.”

At the 2012 Republican National Convention, GOP running mate Paul Ryan described Romney as “not only a defender of marriage, he offers an example of marriage at its best.”

“Culture, what you believe, what you value, how you live matters,” Romney told graduates of Liberty University. “So it is today with the enduring institution of marriage. Marriage is a relationship between on man and one woman.” (The video is embedded on this page. Visit our video library for more videos.)
