LAWRENCE, Kan. (AP) — The mayor of Lawrence is set to join a national effort that supports marriage equality for gay couples. The Lawrence Journal World reports city commissioners are scheduled to authorize Mayor Jeremy Farmer to join the Mayors for the Freedom to Marry coalition at their Tuesday meeting. More than 450 members have joined the coalition, which lobbies for an end to laws that prohibit gay couples from marrying. Farmer, who was sworn in as mayor in early April, said he is confident that such a change is supported by a majority of Lawrence residents. Mayors are asked to sign a statement that supports same sex-marriage and affirms how a community can be enriched by diversity.
