The Senate voted 22-13 at 11:20 p.m. on a budget amendment sponsored by Sen. Bill Diamond, D-Windham.

The amendment fully restores the funding for the Office for Program Evaluation and Government Accountability. The budget had proposed to cut $1.2 million from the office, and reduce staff from seven to two.

The amendment also makes several changes to the budget, including calling for a $150,000 study of the state’s program that provides health insurance to childless adults. It also requires legislators to pay 5 percent of their own health insurance.

In addition, it does not allow the state treasurer to sell $9 million in securities to raise money for the budget.

After the vote, Senate President Beth Edmonds, D-Freeport, said there are 17 other amendments to consider.

“Don’t think of going home yet,” she said.
