CONCORD, N.H. (AP) — New Hampshire senators set the stage Tuesday for a fight with the House and governor over a key measure in President Barack Obama’s health care law — expanding coverage to the state’s poorest uninsured adults next year.

The Senate’s budget panel recommended establishing a study commission rather than expanding Medicaid to cover about 58,000 of the state’s poorest adults under the federal Affordable Care Act. Senate Republican leaders balk at expansion for fear that federal funding will fall short of promises.
