The Obama campaign on Thursday released a video criticizing Mitt Romney for his opposition to gay marriage.

In the nearly 2-minute video, Obama's recent endorsement of gay nuptials is contrasted against Romney's opposition.

“Same-sex couples should be able to get married,” Obama is seen saying.

“I indicated my view, which is I do not favor marriage between people of the same gender and I don't favor civil unions if they are identical to marriage other than by name,” Romney is seen saying.

The video goes on to say that Romney would deny health insurance to the partners and children of gay workers, adoption rights to gay couples, and emergency medical decisions to partners.

Video of former President George W. Bush saying he supports civil unions includes the tagline, “Even President Bush supported civil unions.”

Romney is also seen saying he supports a federal amendment banning gay marriage.

“Calling it marriage creates a whole host of problems for families for the law for the practice of religion, for education. Let me say this: 3,000 years of human history shouldn't be discarded so quickly,” Romney says during a GOP debate. (The video is embedded in the right panel of this page.
