The U.S. Supreme Court is confronting the issue of same-sex marriage for a second day in a row today. Justices will hear arguments on the constitutionality of the Defense of Marriage Act that denies federal benefits to legally married same-sex couples. On Tuesday, the justices considered the legality of California’s Proposition 8 ban on same-sex marriage. Remarks from the justices suggested they are wary of endorsing a broad right for same-sex couples to marry, despite what many marriage equality advocates had hoped.
