The Delaware senate approved a bill legalizing gay marriage on Tuesday, paving the way for it to become the 11th U.S. state to extend marriage rights to same-sex couples.
The state's lower house has already approved the measure. The governor has said he will sign it into law.
Delaware's vote follows a successful effort to legalize same-sex marriage in Rhode Island last Friday. Gay marriage bills are also under consideration in Minnesota and Illinois.
