DENVER (AP) — Supporters of same-sex marriage in Colorado are celebrating their legal victory but also trying to help advance their cause elsewhere.

Elected officials, clergy, and others including Tim Gill and representatives of the ACLU and NAACP say they’ll rally at the 10th Circuit Court of Appeals Monday at 5:30 p.m.

The gathering is sponsored by Why Marriage Matters Colorado. Director Wendy Howell says they not only want to celebrate marriage equality here but they also want to see same-sex marriage legalized across the country.

Gay marriage is legal in Colorado following 10th Circuit rulings against gay marriage bans in Oklahoma and Utah and a federal court’s ruling against Colorado’s ban.

Kansas and Wyoming, also covered by the 10th Circuit, are so far refusing to marry gay couples.
