Gov. Phil Murphy says he'll veto any budget sent to him by state legislators if it relies on "unverified" savings and other "gimmicks."

The governor made the announcement during a news conference Monday, the same day lawmakers plan to unveil their proposals.

Hearings are then expected Tuesday, and a vote on Thursday.

Murphy says lawmakers are proposing $1 billion in unsustainable and temporary revenue, along with $450 million in new spending.

Senate President Steve Sweeney said Friday he would advance a budget that substitutes the governor's proposed income and sales tax increases for a surcharge on businesses while adding millions of dollars more in other spending.

The budget comments come as Murphy and the Democrat-led Legislature approach a June 30 deadline to enact a balanced budget.
