The Arkansas Supreme Court has halted same-sex marriages one week after a state judge struck down a ban on marriage equality. Hundreds of couples obtained licenses in the days after the initial ruling. But Arkansas justices put those unions on hold Friday pending the outcome of a state appeal. The case is expected to reach the U.S. Supreme Court, which set off a wave of state marriage equality rulings after overturning to the Defense of Marriage Act last year. Idaho also saw its marriage equality ban struck down last week, but same-sex marriages have also been put on hold as a court weighs a state request to appeal.
