A gay marriage bill in Rhode Island will face its final legislative hurdle on Wednesday as the Senate takes up the issue.

“Today, we'll know the fate of marriage equality in #RI,” Rhode Islanders United for Marriage, the coalition of groups lobbying for passage of the bill, messaged in a tweet.

The move comes a day after the Senate Judiciary Committee approved the bill with a 7-4 vote and rejected a second related bill which sought to allow voters to decide the issue.

For nearly two decades a marriage equality bill has been introduced in the Rhode Island General Assembly. But the nation's smallest state remains the only New England state which does not allow gay and lesbian couples to marry. Two years ago, lawmakers approved a civil unions bill.

The House overwhelmingly approved the measure in January and it has the support of Governor Lincoln Chafee, an independent.

If the Senate approves the bill, a largely procedural vote is still necessary in the House.
