Washington Governor Chris Gregoire will sign the state's marriage equality bill into law this coming Monday, Reuters reports:
A statehouse signing ceremony in Olympia, Washington's capital, was slated for 11:30 a.m. local time on Monday. The bill won final legislative approval from the state House of Representatives on Wednesday by a vote of 55-43.
The measure will not take effect before early June. Opponents have vowed to seek its repeal at the polls in November, but they cannot begin collecting signatures for a petition to overturn the measure by referendum until it is signed into law.
