Hillary Clinton vehemently opposed the State Department’s 2010 decision to use “parent one and two” instead of “mother and father” on U.S. passport applications, according to a newly released email from her time in office.

“I’m not defending that decision, which I disagree [with] and knew nothing about, in front of this Congress,” Clinton scolded in an email to top aides Cheryl Mills and Jake Sullivan in January of 2011. “I could live [with] letting people in nontraditional families choose another descriptor so long as we retained the presumption of mother and father.”

{mosads}Clinton asked her aides who was behind the decision, and worried about the controversy it would general from conservative media outlets.

“We need to address this today or we will be facing a huge Fox-generated media storm led by Palin et al.,” she wrote, referring to former Alaska Gov. Sarah Palin (R).

The comments could come back to haunt Clinton, whose presidential campaign has made an effort to appeal to gay couples. Her campaign sells multiple souvenir items aimed at LGBTQ supporters, and she will deliver an address at the advocacy group Human Rights Campaign on Saturday.

Clinton previously opposed same-sex marriage before supporting it in recent years, and her opposition to the passport form change could stoke old charges that she is merely bending with the political winds.

The change in passport forms in late 2010 was made “in recognition of different types of families,” the State Department said at the time.

Gay advocacy groups such as Human Rights Campaign adamantly cheered the news.
