Same-sex marriage a step closer in Washington state

(CNN) - Washington moved closer to being the seventh U.S. state to allow same-sex marriage Monday when a key state senator announced her support.

Mary Margaret Haugen said she would be the 25th vote in the 49-member Senate for the bill. Supporters say the legislation already has a majority behind it in the state House of Representatives, and Gov. Christine Gregoire has said she would sign it if passed.
