"The government does not contend that there are legitimate government interests in "creating a legal structure that promotes the raising of children by both of their biological parents" or that the government's interest in "responsible procreation" justifies Congress's decision to define marriage as a union between one man and one woman. ... Since DOMA was enacted, the American Academy of Pediatrics, the American Psychological Association, the American Academy of Child and Adolescent Psychiatry, the American Medical Association, and the Child Welfare League of America have issued policies opposing restrictions on lesbian and gay parenting because they concluded, based on numerous studies, that children raised by gay and lesbian parents are as likely to be well-adjusted as children raised by heterosexual parents. ... The United States does not believe that DOMA is rationally related to any legitimate government interests in procreation and child-rearing and is therefore not relying upon any such interests to defend DOMA's constitutionality"

""Today, the Department of Justice has filed a response to a legal challenge to the Defense of Marriage Act, as it traditionally does when acts of Congress are challenged," Obama said. "This brief makes clear, however, that my Administration believes that the Act is discriminatory and should be repealed by Congress. I have long held that DOMA prevents LGBT couples from being granted equal rights and benefits. While we work with Congress to repeal DOMA, my Administration will continue to examine and implement measures that will help extend rights and benefits to LGBT couples under existing law."
