The Supreme Court has rejected appeals from state officials in five states (Indiana, Oklahoma, Utah, Virginia and Wisconsin) who were requesting that the Supreme Court uphold state bans on same-sex marriage, bans that have been overturned in lower court rulings.
Mark Sherman is the Associated Press Supreme Court writer. In this video he explains that the Supreme Court's silence means that same-sex marriage has now been expanded from 19 states and the District of Columbia to 30 states.
The Supreme Court could potentially rule on same-sex marriage laws if an appeals court upholds a state ban. There are currently two cases pending in appeals court, including this case in the 6th Circuit Court of Appeals.
