Just before signing the Defense of Marriage Act into law in 1996, President Bill Clinton said, "I have long opposed governmental recognition of same-gender marriages and this legislation is consistent with that position."

Earlier this month, Clinton said he had changed his mind and now thinks Section 3 of the law defining marriage as between a man and a woman is ­unconstitutional. "We understand that, while our laws may at times lag behind our best natures, in the end they catch up to our core values," he wrote in a Washington Post op-ed.
