"The court decided that the desires of adults should trump the needs of children. And that's whats gotten lost in all the politics, all the debate, all the hand-wringing in Washington, D.C." he said on NBC's "Meet the Press."
Huelskamp cited research he says shows children of same-sex parents are worse off than those in a household with a mother and a father as evidence that the Court would end up hurting children with its ruling.
The Supreme Court struck down the Defense of Marriage Act earlier this week, allowing same-sex couples to receive federal benefits previously barred to them.
The ruling has caused backlash among social conservatives, who have pledged to pursue other options to ban same-sex marriage.
Huelskamp is championing one way to do so. He plans to introduce the Federal Marriage Amendment, which would define marriage within the Constitution as between one man and one woman, next month.
He said that, though the Founding Fathers made it "extraordinarily difficult" to amend the Constitution, "that's what we're trying to do."
Some Republicans believe that the GOP must abandon its opposition to gay marriage, as public opinion moves in favor, out of fears it could cost them at the ballot box.
Huelskamp dismissed that as the advice of "professional consultants.”
"These folks have always wanted us to go light and abandon our positions on social issues," he said.
