Lawmakers met behind closed doors for much of Thursday, with no details being revealed on what the final state budget plan will look like.
A conference committee meeting, that was expected to begin at eight in the morning, still had not started by late afternoon. A planned floor session in the Senate was also delayed until the evening hours.
Majority Democrats have said the delays are due to the drafting of the conference committee report, although it remains unclear if there is a deal yet that allows the plan to move forward.
The Senate could still vote on the package tonight, with the Assembly expected to act on Friday.
