Demonstrators stand in front of a rainbow flag of the Supreme Court in Washington, Tuesday, April 28, 2015. The Supreme Court is set to hear historic arguments in cases that could make same-sex marriage the law of the land. The justices are meeting Tuesday to offer the first public indication of where they stand in the dispute over whether states can continue defining marriage as the union of a man and a woman, or whether the Constitution gives gay and lesbian couples the right to marry.
