LINCOLN, Neb. (AP) — The newest attempt to expand health care coverage with Medicaid dollars has reopened an old divide in the Nebraska Legislature.

A coalition of doctors, hospitals, local governments and uninsured residents implored lawmakers Wednesday to advance the bill. Conservative groups and members of Gov. Pete Ricketts’ administration argued before the Health and Human Services Committee that the proposal is unsustainable.

The bill by Sen. John McCollister of Omaha would cover childless adults whose incomes are too high to qualify for regular Medicaid but too low to receive tax subsidies available through the federal health care exchange.

Attempts to expand Medicaid in Nebraska have stalled three times in as many years, and the newest bill is expected to face strong resistance once again.
