Same-sex marriage has been legal in Illinois for a year.
L-B-G-T advocates are celebrating today's Supreme Court ruling that says those unions must be recognized nationwide.
Bernard Cherkasov heads the advocacy group Equality Illinois. He says he remembers crying when other states passed laws banning the recognition of same-sex marriage.
"And so now to see this come full circle, and the Supreme Court recognize the constitutional right of gay and lesbian couples to marriage, it feels so great. I can't tell you just how happy I feel."
Cherkasov says the decision means when gay or lesbian couples travel ... their rights won't change as soon as they cross Illinois' border.
