WASHINGTON (CNN) - Republicans and Democrats continued to spar Sunday over how to pay for health care reform.
Some Democrats rejected a proposal to start taxing health care benefits provided by employers. At the same time, momentum among Democrats seems to be building for Obama's proposal to limit tax deductions for those earning more than $250,000 a year.
Republicans oppose the high cost of health care reform, as well as key components of Democratic proposals including higher taxes on the wealthy. However, some Republicans expressed support for taxing employer-provided benefits of the most expensive health insurance plans.
The bottom line: Little is clear as the White House and Democrats continue to press for a health care reform bill by the end of the year.
