With no GOP help, the Democratic-led New Jersey Assembly narrowly approved legislation legalizing same-sex marriage in the state, a measure that now goes to Republican Gov. Christie, who has vowed to "swiftly" veto it and instead wants a referendum on the issue.

The 42-33 Assembly vote Thursday followed similar approval Monday in the Senate, which voted, 24-16, in favor of the measure. Neither majority is large enough to override a veto.
