Rick Perry has reiterated his support for a constitutional amendment banning gay marriage and his opposition to gay and lesbian couples adopting children.

The 61-year-old Perry made his remarks Saturday at the Thanksgiving Family Forum in Des Moines, Iowa. Also attending the event were Newt Gingrich, Rick Santorum, Herman Cain, Ron Paul and Michele Bachmann. Former Massachusetts Governor Mitt Romney was invited but did not attend. Also not in attendance was former Utah Governor Jon Huntsman, who has not placed an emphasis on Iowa.

The candidates gathered around a dinner table festooned with pumpkins and fall leaves as moderator Frank Luntz kept the conversation flowing for two hours as nearly 3,000 religious and socially conservative activists listened in.

When Tom Minnery, the head of CitizenLink, the political arm of the Christian conservative group Focus on the Family, asked Perry what he would do as president to help faith-based adoption agencies “which are being run out of business because they will only place children in homes headed by mothers and fathers and they will not place those children in homes headed by same-sex couples,” Perry answered that passing the federal marriage amendment would address the issue.

“But until that does pass, as in the state of Texas, a gay couple cannot adopt a child in the state of Texas, so the states have the ability again until there is a federal marriage amendment that clearly states that marriage is between one man and one woman and in that as well you cannot adopt a child unless it is one man and one woman,” Perry answered.
