The New Jersey State Senate voted in favor of a same-sex marriage bill on Monday. The bill is expected to reach the New Jersey State Assembly on Thursday, but Gov. Chris Christie has vowed to veto it. Meanwhile, Washington became the seventh state to legalize same-sex marriage after Gov. Chris Gregoire signed a measure into law Monday. Opponents there have filed a referendum challenging the law. If opponents collect the more than 120,000 signatures required before June 6, the law would be put on hold pending a November vote.
