Gov. Phil Murphy on Sunday signed a $38.7 billion budget without a millionaire’s tax, ending tense negotiations with top Democrats and staving off a government shutdown.

But in a rebuke to legislators, Murphy used his line-item veto authority to cut $48.5 million out of the budget, which totals about half of the spending for legislative add-ons that Murphy has criticized as “pork and Christmas trees.”

In recent weeks, he repeatedly questioned the Legislature’s revenue projections to support the added items, calling it the result of “magic” and “fuzzy” math.

Murphy said he will also hold up to $235 million in appropriations that will only be released if the Legislature’s higher revenue projections bear out.

On Sunday, Senate President Steve Sweeney said their projections are sound, but he also did not signal he planned to override the governor’s line-item vetoes or challenge Murphy’s decision to freeze spending.

“If his word is good and revenues come in and those revenues will be released, I’m OK with that,” Sweeney said.

Despite tensions between Murphy and Sweeney, the budget Murphy signed Sunday reflects a general consensus between the two sides, including $14.6 billion for K-12 education and a record $3.8 billion payment into the state’s public worker pension fund. It also maintains the Legislature’s addition of $75 million in new funding for NJ Transit and a $50 million increase for extraordinary special education.

But the rhetoric wasn’t any friendlier, signaling the fundamental differences between the two won’t be reconciled anytime soon.

On Sunday, Murphy again vowed to pass a millionaire’s tax.

“Is the governor not going to be satisfied until we have the highest tax burden in the nation?” Sweeney asked. “The millionaire’s tax is one tax. It’s not going to solve the problem.”

“We got overwhelmingly what we wanted,” said Murphy, “but this ain’t gonna end today.”
