Des Moines, Iowa (CNN) - Republican presidential candidate Rick Perry has signed the controversial marriage pledge from a social conservative group in Iowa, a spokeswoman said.
"I have received the signed copy," Julie Summa, Director of Marketing for The Family Leader said. Summa said the Texas governor's campaign submitted it electronically on Monday and the governor did not modify the document before signing it.
Programming note: GOP presidential candidates face off at 8 p.m. ET Tuesday, November 22, in the CNN Republican National Security Debate in Washington, D.C.
According to the pledge's text, signers "solemnly vow to honor and cherish, to defend and uphold the institution of marriage as only between one man and one woman."
Signers also vow to: remain faithful to their spouses, oppose any "redefinition" of marriage, such as that between same-sex couples; and embrace a federal marriage amendment to the U.S. Constitution.
Language in the original document, put out in July, sparked some controversy.
Its preamble asserted that African-American children, who were born into slavery, were better off than today's black children. The group later removed that language.
GOP presidential candidates Michele Bachmann and Rick Santorum signed the original document, raising some eyebrows. Though the controversial language on black children was placed high in the preamble, it's not clear if Bachmann or Santorum saw it before signing. Both candidates later clarified their support of the pledge: Santorum saying he agreed with The Family Leader's decision to remove the language on slavery and Bachmann's campaign stressing the congresswoman believed that "slavery was horrible."
The Des Moines Register first reported Perry's signing the marriage vow.
This comes two days after the Texas governor attended the group's "Thanksgiving Family Forum" along with five other GOP presidential candidates.
The Family Leader is influential in Iowa, holding some sway over many social conservatives – a key voting block in the state. Summa said her group has not yet decided whether signing the document is an absolute must for a candidate to earn its support. But the spokeswoman added: "We would certainly want a candidate to sign the pledge, before we make an endorsement."
