Governor Deval Patrick is concerned about the $170 million in additional spending in the budget, but stopped short of making anything resembling a warning.

Millions of dollars in pork was packed into budget amendments last week that increased state spending by $170 million, drawing stern warnings from Gov. Deval Patrick, who had sought to eliminate legislative earmarks from the budget.

In an interview yesterday, Patrick refused to say whether he would veto the spending, but he made clear he is concerned about the House’s plan to tap into more than $600 million in reserves and “rainy day” funds.

“At the end of the day, we have to deal with the revenue side as well,” Patrick said, referring to sluggish tax collections. “We’ll take up (legislative earmarks) as they come. I still think there is duplication, particularly in administrative overlap, that is at risk from earmarks generally.”
