CHEYENNE, Wyo. (AP) — Scores of supporters of legalizing same-sex marriage in Wyoming gathered in Cheyenne on Monday to kick off a public education campaign.

Four same-sex couples and Wyoming Equality, a gay rights advocacy group, filed a lawsuit earlier this month against Wyoming Gov. Matt Mead and other officials. The lawsuit challenges Wyoming law specifying marriage may only exist between one man and one woman.

Jeran Artery of Wyoming Equality said Monday at the State Capitol that Wyoming must live up to its motto of being the "Equality State."

The push to recognize same-sex marriage in Wyoming comes as a federal court in Denver is set to hear arguments from the state of Utah next month. Utah is appealing a federal judge's recent ruling that its prohibition against same-sex marriage is unconstitutional.
