Episcopal Bishop Gene Robinson is expected to testify today in favor of a bill allowing gay marriage in New Hampshire.
The U.S. Episcopal Church consecrated Robinson as its first openly gay bishop in 2003, prompting a rift with the global Anglican Communion, which the church belongs to.
The bill comes a year after a law granting civil unions to gay couples took effect in New Hampshire.
The House Judiciary Committee is holding a hearing on the bill and others, including one that would define marriage as a union between one man and one woman, and others that would tweak the civil unions law.
