NEW YORK (AP) Hillary Rodham Clinton is calling for the repeal of the so- called "Cadillac tax," a part of the health care law that could raise costs for consumers, large corporations and union members when it takes effect in 2018.

Clinton says her proposal aims to "build on the progress" made under President Barack Obama's Affordable Care Act. But she's pushing to eliminate the tax because, she says, "too many Americans are struggling to meet the cost of rising deductibles and drug prices."

Revenue from the tax is designed to offset increased costs under the health law. Clinton says she will propose a plan to make up the lost revenue.

The tax is opposed by many unions, a powerful force in the Democratic party that largely have held off endorsing Clinton.
