The U.S. Supreme Court heard arguments on the controversial issue Tuesday. Whatever the judges decide could impact the lives of same-sex couples for years to come. Many are calling it a turning point in what's been a long fight.
On the state level, couples could soon get the chance to marry. On the federal level, this court case will decide whether the federal government would recognize those marriages.
The court held the first of two days of arguments. It's an event Peggy Patty has her eyes glued to.
She married her partner in Iowa in 2009. Since that marriage isn't recognized by the federal government, the couple could lose out on benefits like social security.
Tuesday's arguments focused more on California Proposal 8. Voters in California passed the proposal allowing same-sex marriage, but then a lower court struck it down.
Wednesday, the Supreme Court will argue the Federal Defense of Marriage Act. The Obama Administration has chosen not to defend it, so House republicans are stepping up in court.
