Says Justice Antonin Scalia.
You may also be interested to know that he reveals what he thinks about whether Congress has the power to regulate marriage: "No, I don't see anything in there. I don't see any authorization of the federal government to do that." So presumably, in Scalia's view the Defense of Marriage Act, which among other things, absolves states of the obligation to respect same-sex marriages made in other states, is unconstitutional. Someone asks the obvious follow-on question whether the Constitution obligates a state to recognize another state's same-sex marriages, and he judiciously holds his tongue.
