Lawsuit challenges marriage ban in Wyo.

A lawsuit filed last week by four same-sex couples and the group Wyoming Equality seeks to overturn the state's ban on marriage equality and compel the state to recognize same-sex marriages performed elsewhere. 

 "Wyoming has a proud history of being the 'Equality State,' and its refusal to allow same-sex couples to marry is contrary to the core values of our state," said Jeran Artery, chairman of Wyoming Equality.
