New Jersey Senate President Stephen Sweeney on Friday predicted that lawmakers will approve a proposed gay marriage bill, but added that he expects Republican Governor Chris Christie will veto the measure.

Sweeney made his remarks during an appearance on WNYC's the Brian Lehrer Show.

Both houses of the New Jersey Legislature are expected to vote on the bill next week: the Senate on Monday and the Assembly on Thursday.

“It is absolutely going to pass on Monday, and I expect it to pass the Assembly on Thursday, and it's going to go the governor's desk,” he said.

Sweeney voted against a marriage equality bill in 2010, but has since reversed course, calling his original vote “wrong.”

He also conceded that he does not have the 27 votes in the Senate needed to override the governor's veto, but pledged his support to the effort.

“If the governor vetoes the bill, we're gonna fight to override the governor,” Sweeney said. “I have two years to do it almost, so that gives us plenty of time to work on people.”
