Massachusetts Representative Barney Frank believes support for gay marriage in the Democratic Platform is a “good thing politically & morally.”

Democrats meeting in Charlotte, North Carolina on Tuesday approved a party platform which includes support for gay nuptials.

In July, the 72-year-old Frank married his partner Jim Ready in Massachusetts, becoming the first sitting member of Congress to enter into a marriage with a member of the same sex.

Appearing on CNN, Frank, who in 1987 became the first congressman to voluntarily come out gay, discussed what the party's move means to him.

“I feel very good that the party I worked for so many years now says, 'You know what, we're going to treat everybody in this country fairly and equally,'” Frank said. “And I think, by the way, it's going to be a good thing politically & morally.”

The legalization of gay marriage “has no negative effect on anybody, and a positive effect on a lot of us,” he added.

Frank also said that he was skeptical of Mitt Romney's plans for the economy, saying that under his tenure as governor of Massachusetts the state didn't experience much economic growth. (The video is embedded on this page. Visit our video library for more videos.)
