Arguments on the Defense of Marriage Act at the Supreme Court have ended after nearly two hours.
The federal law means federal tax, Social Security, pension and bankruptcy benefits, and family medical leave protections do not apply to gay and lesbian couples.
Today's session comes a day after the court heard arguments over California's Proposition 8, which defines marriage for that state as being between only a man and a woman. The overriding question in that case is whether the Constitution's guarantee of equal protection under the law prevents states from defining marriage.
The justices are expected to rule on the cases by mid-June.
