CHEYENNE, Wyo. (AP) - Four gay couples and a gay rights advocacy group have sued Gov. Matt Mead and other officials in an attempt to get Wyoming to recognize gay marriage.

They filed the suit Wednesday in Laramie County District Court.

Wyoming law specifies that marriage occurs between males and females. The lawsuit seeks to require state officials to both recognize gay marriages performed outside Wyoming and to perform gay marriage inside the state.

The plaintiffs are the Cheyenne-based gay rights group Wyoming Equality and four couples - two who were married outside Wyoming and two who want to wed in Wyoming.

Mead spokesman Renny MacKay said he hadn't seen the lawsuit and had no comment.
