(CNN) - Vermont's House and Senate voted Tuesday to override the governor's veto of a bill legalizing same-sex marriage in the state.
The Senate voted 23-5 to override Gov. Jim Douglas' veto, according to the Senate office. Shortly afterward, the House overrode the veto on a 100-49 vote. The votes surpassed the number needed - two-thirds of those present - to override the veto.
The action makes Vermont the fourth state to legalize same-sex marriages. The others are Massachusetts, Connecticut and, as of last week, Iowa.
Douglas vetoed the bill on Monday. "Vermont's civil union law has afforded the same state rights, responsibilities and benefits of marriage to same-sex couples," the governor wrote in a letter to David Gibson, secretary of the Senate. "Our civil union law serves Vermont well and I would support congressional action to extend those benefits at the federal level to states that recognize same sex unions. But I believe that marriage should remain between a man and a woman."
