On Monday, a U.S. District judge threw out a challenge to the federal Defense of Marriage Act (DOMA) on a technicality. DOMA defines marriage as the union of one man and one woman.
Pro-family said the plaintiffs will likely re-file.
Brian Raum, senior legal counsel with the Alliance Defense Fund, said he's confident, no matter what happens, that DOMA will stand.
"Marriage is not just any two people in a committed relationship," he said. "Americans understand and believe that there's more to marriage than that."
