Illinois is about to join the ranks of states allowing same-sex marriage.
Gov. Pat Quinn is expected to sign a bill Wednesday making Illinois the 16th state to legalize gay marriage. The event will be held at the University of Illinois at Chicago.
Illinois allowed civil unions in 2011. But it was a bumpy road to same-sex marriage in President Barack Obama's home state.
The Illinois Senate approved the measure in February, but the House sponsor said he didn't have the votes. It wasn't called until this month and passed by a close margin.
Those who opposed the measure included some of Illinois most well-recognized religious leaders.
Same-sex couples will be allowed to wed starting in June.
