Sen. Clayton Hee calls it "a defining moment as an elected official."
On Saturday, Hee, Chair of Judiciary Committee, recommended the Senate pass the Hawaii Senate pass a bill allowing same-sex marriage.
"The fact that the bill wasn't amended allowed us to make the recommendation today," said Hee.
Tensions were high Friday as the House vote took more than 12 hours to pass the bill 30 to 19.
However, Hee predicts the hearing with senate members on Tuesday will be swift and predictable.
"I have the status sheet and there were 29 amendments offered by the House. I would be very surprised if that were to occur in the Senate. That's simply not how we conduct ourselves," said Hee.
The lone Republican in the Senate, Sam Slom, who voted against the bill, said he will make an opposing comment and will vote no again, but he thinks the vote will stay the same as it did on its third hearing -- 21 to 4 in favor.
Hee said security will remain tight. There will be the same separated spaces and tight security in place as Friday night.
"Quite frankly, I don't know why it would come to that, but unfortunately the human dynamics up to this point that those kinds of preventions are necessary," said Hee.
Same-sex marriage supporters marked today's recommendation as a great day.
"Now we hope the rest of the Senate members are as happy with the outcome as we are," said Jacce Mikulanec with Equality Hawaii.
Others aren't so anxious for Tuesday.
"I think it's the Legislature not listening to people and 'ram-rodding' stuff down our throats again," said Larry Litoto, who is opposed to the bill.
The bill will be heard by the Senate at 10 a.m. Tuesday. If it passes, it heads to Gov. Neil Abercrombie who could sign it as soon as Wednesday morning.
