(CNN) - Texas Gov. Rick Perry voiced support for a federal marriage amendment Wednesday, a departure from earlier comments in support of states' rights.
The Republican governor, who is considering a run for the White House in 2012, said he supports a federal amendment to the Constitution defining marriage as a union between one man and one woman.
"I support the federal marriage amendment and I also support the same with the issue of abortion," Perry said in an interview on the Christian Broadcasting Network. "I also support that same process for a balanced budget amendment to the United States Constitution."
At a dinner in Aspen in July, Perry responded to a vote in New York that legalized same-sex marriage, saying "That's New York and that's their business, and that's fine with me."
In a later interview with Family Research Council President Tony Perkins, Perry further clarified his remark by repeating his commitment to the 10th amendment and his belief that marriage should be between a man and a woman.
"It's fine with me that a state is using their sovereign rights to decide an issue," Perry said. "Obviously gay marriage is not fine with me. My stance hasn't changed."
The longest serving governor in Texas history received criticism from Republican presidential candidate Rick Santorum, who is one of many candidates running in part on their socially conservative record that will prove important to early presidential primary and caucus voters.
In the interview on CBN, Perry again emphasized his support of states' rights.
"Wouldn't America be stronger economically if we removed all those strings that have been attached to everything," Perry said. "Remove all those strings and let these states go out there and be laboratories of innovation."
And as expected, Perry said he will make a final decision about a presidential bid in the next few weeks.
"I have no idea what God's plans are for me, but I'm going to try to be as faithful to him as I can be," Perry said.
A spokesman for Perry did not immediately respond to a request for comment.
