(CNN) - Four days after the Justice Department filed a brief strongly supporting the Defense of Marriage Act, openly gay Rep. Barney Frank said the Obama administration made a "big mistake" and is calling on the president to clearly explain his views on the matter.
"I think the administration made a big mistake. The wording they used was inappropriate," the Massachusetts Democrat told the Boston Herald during an interview published in the paper's Wednesday edition.
Update: Rep. Frank has since said his comments were based on a flawed description of the administration's brief and believes President Obama does not deserve criticism for the document. (full statement below)
Many gay activists have called on Frank and other gay members of Congress to speak out against the recent DOJ brief, which appeared to equate gay marriage to incest in its reasoning that states have the right not to recognize gay marriages from other states.
The brief says states favor heterosexual marriages because they are the "traditional and universally recognized form of marriage," and specifically argued that the Constitution's "full faith and credit" clause - whereby states have to respect the "public acts, records, and judicial proceedings" - does not apply to gay marriage just as it does not apply to mariages involving incest.
"I've been in touch with the White House and I'm hoping the president will make clear these were not his views," Frank also said.

Rep. Jared Polis - another openly gay member of Congress - also criticized the Obama administration late Tuesday, saying in a statement he was "shocked and disappointed."
"Comparing my loving relationship with my partner, Marlon, to incest was unconscionable coming from a president who has called for change," he said.
The brief has set off a firestorm among prominent members of the gay community - already frustrated with the president for not taking steps to overturn the military's policy of "Don't Ask, Don't Tell." While campaigning for the Democratic presidential nomination last year, Obama said he was against both the Don't Ask, Don't Tell policy and the Defense of Marriage Act.
"The brief …could have been written by the Rev. Pat Robertson," wrote former Clinton adviser David Mixner, now a prominent Democratic fundraiser. "Using the worst of stereotypes, it intimates that we don't have constitutional guarantees, invokes scenarios of incest, of children and advocates that we don't have the same rights as others who have struggled for civil rights. "
"What in the hell were they thinking? Or is that their thinking?" Mixner added.

Mixner is one of several gay Democrats to drop out of a Democratic National Committee fundraiser next week - co-hosted by Reps. Frank and Polis - featuring Vice President Biden and honoring the lesbian, gay, bisexual, and transgender community.
"How will they ever take us seriously if we keep forking out money while they harm us?" Mixner wrote.
The DNC did not respond to CNN's request for comment.
UPDATE: In a Thursday statement, Frank walked back his earlier remarks.
Full statement follows:
“When I was called by a newspaper reporter for reaction to the administration’s brief defending the constitutionality of the Defense of Marriage Act, I made the mistake of relying on other people’s oral descriptions to me of what had been in the brief, rather than reading it first. It is a lesson to me that I should not give in to press insistence that I comment before I have had a chance fully to inform myself on the subject at hand.”
“Now that I have read the brief, I believe that the administration made a conscientious and largely successful effort to avoid inappropriate rhetoric. There are some cases where I wish they had been more explicit in disavowing their view that certain arguments were correct, and to make it clear that they were talking not about their own views of these issues, but rather what was appropriate in a constitutional case with a rational basis standard – which is the one that now prevails in the federal courts, although I think it should be upgraded.”
“It was my position in that conversation with the reporter that the administration had no choice but to defend the constitutionality of the law. I think it is unwise for liberals like myself, who were consistently critical of President Bush’s refusal to abide by the law in cases where he disagreed with it to now object when President Obama refuses to follow the Bush example. It is the President’s job to try to change the law, but it is also his obligation to uphold and defend it when it has been enacted by appropriate processes. It would not be wise, in my judgment, for those of us who are gay, lesbian, bisexual or transgender, or who sympathize with the fight for our rights, to argue for a precedent that says that executives who disagreed politically with the purpose of the law should have the option of refusing to defend it in a constitutional case.”
“I strongly opposed DOMA when it was adopted and I will continue to fight for changes. I support very strongly the lawsuit brought by the people at Gay & Lesbian Advocates and Defenders (GLAD) that make the cogent argument that DOMA’s provision denying federal recognition of same-sex marriages blatantly violates the equal protection clause. And I will work with the Obama administration as they have promised to do to enact laws protecting LGBT people from hate crimes, from job discrimination, and from discrimination in the military. I will also be critical when I think inappropriate language is used. But after rereading this brief, I do not think that the Obama administration should be subject to harsh criticism in this instance.”
