Washington legislators passed a bill that legalizes same-sex marriage Wednesday, making it the seventh state to do so, officials said.
The law was passed after a 55-43 vote that included two Republicans that supported the bill, according to CBS.com.
The law will go into effect in June, unless the opposition is able to put it on the November 2012 ballot.
Gov. Chris Gregoire is expected to sign the bill next week, saying it is "a major step toward completing a long and important journey to end discrimination based on sexual orientation."
Some Republicans argued the bill goes against the tradition of marriage, according to CBS.
Rep. Jay Rodne said, "It contravenes human nature and it will hurt families and children."
According to CNN.com, The National Organization for Marriage is seeking to have the voters vote on it as a referendum in November. In order to do so, they will need 120,577 signatures.
According to a University of Washington poll, 55 percent of Washington respondents said they would vote to uphold the law.
Once Gov. Gregoire signs the bill, couples will need to wait 90 days for the law to go into effect.
