Gov. Dannel Malloy finally signed a state budget Tuesday after months of failed negotiations in Hartford.

The governor played no role in the negotiations of the bipartisan bill.

"I want to be clear, this is not a document I would have negotiated,"  Malloy said at a news conference after signing the budget. "And I do have very real concerns about many aspects of it."

The governor was so concerned about the hospital tax -- and whether it's legal -- that he line-item vetoed $1 billion in payments to hospitals. He urged lawmakers to return to Hartford soon to address that part.

"The language on its face defies the approval process, meaning that we could be out of pocket by over a billion dollars," he said.

Last week the plan received broad support from legislators of both parties in closed-door negotiations, and lawmakers have said they're open to making changes to the hospital plan.

"I think we definitely have to come back and do something." said state Sen. Len Fasano, a North Haven Republican. "Whether that is an amendment to the document or an override, I think the leaders will have a conversation."

It contains no increases to sales or income taxes, but it still manages to fully fund pensions, Malloy said. It also creates a new formula for school funding.
