House Assistant Minority Leader James Clyburn is the latest Democrat to express support for gay marriage following President Barack Obama's backing.

Appearing on MSNBC, Clyburn, who in 1996 voted for the Defense of Marriage Act (DOMA), which forbids federal agencies from recognizing the legal marriages of gay and lesbian couples, said that he had also “evolved” on the issue.

“I, like the president, have evolved to a point of marriage equality,” Clyburn said. “I have not always been there. I grew up in a parsonage, a fundamentalist Christian parsonage, and I grew up with that indoctrination. And I have grown to the point that I believe that we have evolved to marriage equality.”

But the South Carolina Democrat disagreed with Obama on his approach to the issue.

“If we consider this to be a civil right – and I do – I don't think civil rights ought to be left up to a state-by-state approach. I think that we should have a national policy on this.”

House Minority Whip Steny Hoyer, a Maryland Democrat, also came out in favor of gay nuptials following the president's announcement. Meanwhile, Senate Majority Leader Harry Reid, a Democrat from Nevada, inched closer to full support, saying in a statement that he personally believes marriage is a heterosexual union but adding that “in a civil society, I believe that people should be able to marry whomever they want.”
