INDIANAPOLIS (AP) _ Gay rights supporters will see off some of the plaintiffs in Indiana's dispute over same-sex marriage as they make their way to Chicago for legal arguments before the 7th U.S. Circuit Court of Appeals.

The day begins with a rally 9 a.m. Monday at the Indianapolis City Market sponsored by Hoosiers Unite for Marriage. Rallies also are scheduled in Lafayette, Munster and Chicago, where the federal court hearing will be conducted Tuesday.

Hoosiers Unite for Marriage spokeswoman Jennifer Wagner says some of the couples involved in the case will be traveling to Chicago in a caravan.

The court will be hearing arguments in a combined appeal by Indiana and Wisconsin of federal district court rulings that struck down each state's ban on same-sex marriage.
