AUGUSTA, Maine (AP) — A Republican-backed health care overhaul bill aimed at encouraging competition and driving down insurance premiums in Maine has been put on hold until Monday.

Republicans and Democrats debated through the night before the Senate decided shortly before 1 a.m. Friday to adjourn without a final vote.

The House on Thursday approved the bill along party lines, sending it back to the Senate. After contentious debate, the Senate opted to adjourn and take up the matter next week.

Republicans say the bill will lead to greater choice and competition to hold down health insurance costs in Maine. But Democrats say the bill is being rushed and will result in rural and older residents paying disproportionately higher rates.
