"I think it's getting worse, not better," House GOP Whip Kevin McCarthy, R-Calif., said.

The Boehner camp again said it's up to the White House to proffer additional spending cuts to programs like Medicare. The White House countered that Republicans still need to cave on raising tax rates for the rich.

"Where are the president's spending cuts?" Boehner said on the House floor. "The longer the White House slow-walks this process, the closer our economy gets to the fiscal cliff."

In rebuttal, the White House swiftly detailed numerous proposals Obama has made to cut spending, including recommendations to cull $340 billion from Medicare over a decade and an additional $250 billion from other government benefit programs.

Obama remains determined that tax rates rise on family income exceeding $250,000, a move Republicans say would strike many small businesses that are engines of new jobs and file as individuals when paying their taxes.

House Minority Leader Nancy Pelosi said Wednesday that a bipartisan deal to avert a "fiscal cliff" is more likely if Democrats and Republicans don't try to over-reach on spending cuts.

The California Democrat, appearing on "CBS This Morning," said Congress and the White House need to agree on a provisional plan for taxes and spending. "Let's do something now," she said.

Pelosi says Democrats want to ensure that senior citizens aren't harmed, and she called Boehner a "well-intentioned" person. But she also said the GOP was pushing too hard on a Medicare overhaul, asking, "Is it just a trophy that the Republicans want to take home?"

"Get it done," she said, "and make corrections and expansions on it next year."

Two weeks before the year-end holidays, time to find agreement was short, but not prohibitively so.

"I think it's going to be extremely difficult to get it done before Christmas, but it could be done," Senate Majority Leader Harry Reid, D-Nev., said.

Boehner's office took the step — unusual in secretive talks — of announcing that Republicans "sent the White House a counteroffer that would achieve tax and entitlement reform to solve our looming debt crisis and create more American jobs."

Democrats have watched with satisfaction in recent days as Republicans struggle with Obama's demands to raise taxes, but Reid privately has told his rank and file they could soon be feeling the same distress if discussions grow serious on cuts to benefit programs.

In an ABC interview, Obama did not reject a Republican call to raise the age of Medicare eligibility from 65 to 67, a proposal many Democrats strongly oppose.

The proposal is "something that's been floated," Obama said, not mentioning that he had tacitly agreed to it in deficit-reduction talks with Boehner more than a year ago that ended in failure.

"When you look at the evidence, it's not clear that it actually saves a lot of money," Obama said. "But what I've said is, let's look at every avenue, because what is true is we need to strengthen Social Security, we need to strengthen Medicare for future generations, the current path is not sustainable because we've got an aging population and health care costs are shooting up so quickly."

Obama's plan would raise $1.6 trillion in revenue in part by raising tax rates on incomes over $200,000 for individuals and $250,000 for couples. He has recommended $400 billion in spending cuts over a decade.

He also is seeking extension of the Social Security payroll tax cut due to expire Jan. 1, a continuation in long-term unemployment benefits and steps to help hard-pressed homeowners and doctors who treat Medicare patients.

The White House summary noted that Obama last year signed legislation to cut more than $1 trillion from government programs over a decade, and was proposing $600 billion in additional savings from benefit programs.

Boehner's plan, in addition to calling for $800 billion in new revenue, envisions $600 billion in savings over a decade from Medicare, Medicaid and other government health programs, as well as $300 billion from other benefit programs and another $300 billion from other domestic programs.

It would trim annual increases in Social Security payments to beneficiaries and gradually raise the eligibility age for Medicare.
