Gay marriage supporters are launching a $2 million statewide campaign to approve same-sex marriage in Illinois.
Illinois Unites for Marriage is a coalition representing gay rights, civil rights and political groups.
In a statement Tuesday, the group says it will place 15 field organizers throughout the state to engage supporters. They plan to target legislators who oppose a measure to lift Illinois' ban on same-sex marriage.
The Illinois Senate passed the bill in February. It wasn't called for a vote in the House because the bill's sponsor said it didn't have the votes to pass.
Jim Bennett is chairman of the coalition. He says the next few months are critical because lawmakers could take up the bill in the fall.
Opponents say marriage should be between a man and woman.
