New York's state budget will be at least three weeks late as lawmakers approved on Thursday yet another stopgap spending bill to fund the government through Monday.

Lawmakers are set to leave Albany for the next three days amid ongoing disagreements over a final budget deal, with issues ranging from making changes to New York's 2019 bail law and a statewide housing plan remaining up in the air.

Gov. Kathy Hochul and top Democrats in the Legislature are yet to also resolve key issues ranging from mass transit funding, taxes and whether to expand charter schools in the state.

"I'm very optimistic. We're putting the budget together. We're negotiating," said state Sen. Tim Kennedy, a Democrat from Buffalo. "It's hundreds of billions of dollars and at the end of the day we're making sure it's the right budget for the people of New York."

Republicans, meanwhile, criticized the process, accusing Democrats who control all branches of state government of negotiating in secret.

"The last public budget hearing was almost two months ago," said Sen. Mark Walczyk, a Republican from Watertown. "When leaders like Senate Majority Leader Andrea Stewart-Cousins says there's so much policy packed into this budget, that should give everyone a lot of concern."

The budget was initially due April 1, the start of New York's fiscal year. Lawmakers and Hochul agree to approve temporary spending measures every few days in order to fund payroll for state employees and other expenses of the government.

Andrew Rein, the watchdog organization Citizens Budget Commission, called the lack of resolution a disappointment. 

"Budget negotiations thus far have focused on a few important policy areas, but not much about the billions of dollars and cents in the budget. Policy choices are critical to New Yorkers, and the budget often serves as the cudgel to get deals done," he said. "But how the State plans to raise and spend the people’s money must be a priority; choices made will affect New Yorkers’ lives for years to come."
