Senate Majority Leader Harry Reid and Senate Republican leader Mitch McConnell remained at odds on such key issues as the income threshold for higher tax rates and how to deal with inheritance taxes, among other issues. McConnell complained that Reid had yet to respond to a Republican offer made Saturday evening and reached out to Vice-President Joe Biden, a longtime friend and former senator, in hopes of breaking the impasse.
Biden assumed the lead role for Democrats, and a McConnell spokesman said the Kentucky Republican and the vice-president were expected to negotiate by telephone into the night.
One sign of progress came as Republicans withdrew a long-discussed proposal to slow future cost-of-living increases for Social Security recipients as part of a compromise to avoid the cliff. Democrats said earlier Sunday that proposal had put a damper on the talks, and Republican senators emerging from a closed-door caucus meeting said it is no longer part of the equation.
"I was really gratified to hear that Republicans have taken their demand for Social Security benefit cuts off the table. The truth is they should never have been on the table to begin with," Reid said late Sunday afternoon. "There is still significant distance between the two sides, but negotiations continue."
At stake are sweeping tax hikes and across-the-board spending cuts set to take effect at the turn of the year. Taken together, they've been dubbed the fiscal cliff, and economists warn the one-two punch — which leaders in both parties have said they want to avoid — could result in a big jump in employment, turmoil in financial markets and send the still-fragile economy back into recession.
The U.S. faces the fiscal cliff because the tax rate cuts enacted in 2001 and 2003 during President George W. Bush's administration expire on Dec. 31. The pending across-the-board reductions in government spending, which will slice money out of everything from social programs to the military, were put in place last year as an incentive to both parties to find ways to cut spending. That solution grew out of the two parties' inability in 2011 to agree to a grand bargain that would have taken a big bite out of the deficit.
Unless Obama and Congress act to stop them, about $536 billion in tax increases, touching nearly all Americans, will begin to take effect in January. That will be coupled with about $110 billion in spending cuts, about 8 per cent of the annual budgets for most federal departments.
Sen. Dick Durbin, the No.2 Senate Democrat, said the two sides remained at odds over the income threshold for higher tax rates and tax levels on large estates. Republicans said that Democratic demands for new money to prevent a cut in Medicare payments to doctors and renew jobless benefits for the long-term unemployed should be financed with cuts elsewhere in the budget. Medicare is the government program that provides health care coverage to the elderly.
Republicans also balked at a Democratic proposal to use new tax revenues to shut off the across-the-board spending cuts, known as a sequester in Washington-speak.
Reid said he's been in frequent contact with President Barack Obama, who in a televised interview blamed Republicans for putting the shaky U.S. economy at risk.
"We have been talking to the Republicans ever since the election was over," Obama said in the interview that was taped Saturday and aired Sunday on NBC's "Meet the Press." ''They have had trouble saying yes to a number of repeated offers."
"The mood is discouraged," said Sen. Joe Lieberman, a Connecticut independent who caucuses with Democrats. He said he would be shocked if there was a deal Sunday. "The parties are much further apart than I hoped they'd be by now."
The pessimistic turn came as the House and Senate returned to the Capitol for a rare Sunday session. Reid and McConnell had hoped to have a blueprint to present to their rank and file by mid-afternoon.
"I'm concerned with the lack of urgency here. There's far too much at stake," McConnell said. "There is no single issue that remains an impossible sticking point — the sticking point appears to be a willingness, an interest or courage to close the deal."
McConnell and Reid were hoping for a deal that would prevent higher taxes for most Americans while letting rates rise at higher income levels, although the precise point at which that would occur was a major sticking point.
Obama had wanted to raise the tax rate on individuals making more than $200,000 a year and families making more than $250,000 from 35 per cent to 39.6 per cent. In talks with Republican House Speaker John Boehner, he offered to raise that threshold to $400,000.
The estate tax issue was particularly tricky since several Democrats, including veterans like Sen. Max Baucus of Montana, disagree with Obama's proposal to increase the top estate tax rate from 35 per cent to 45 per cent.
Republicans said Democrats pressed to turn off more than $200 billion in the across-the-board spending cuts over the coming two years. This so-called sequester is the punishment for last year's failure to strike a deficit-reducing deal by a "supercommittee" of House and Senate members.
Hopes for blocking across-the-board spending cuts were fading and Obama's proposal to renew the 2-percentage-point payroll tax cut wasn't even part of the discussion.
Obama pressed lawmakers to start where both sides say they agree — sparing middle-class families from looming tax hikes.
"If we can get that done, that takes a big bite out of the fiscal cliff. It avoids the worst outcomes. And we're then going to have some tough negotiations in terms of how we continue to reduce the deficit, grow the economy, create jobs," Obama said in the NBC interview.
Gone, however, is the talk of a grand deal that would tackle broad spending and revenue demands and set the nation on a course to lower deficits. Obama and Republican House Speaker John Boehner were once a couple of hundred billion dollars apart on a deal that would have reduced the deficit by more than $2 trillion over ten years.
Republicans have complained that Obama has demanded too much in tax revenue and hasn't proposed sufficient cuts or savings in the nation's massive health care programs.
Obama upped the pressure on Republicans to negotiate a fiscal deal, arguing that Republican leaders have rejected his past attempts to strike a bigger and more comprehensive bargain.
"The offers that I've made to them have been so fair that a lot of Democrats get mad at me," Obama said.
Boehner disagreed, saying Sunday that the president had been unwilling to agree to anything "that would require him to stand up to his own party."
The trimmed ambitions of today are a far cry from the upbeat bipartisan rhetoric of just six weeks ago, when the leadership of Congress went to the White House on Nov. 16 to set the stage for negotiations to come.
But the deal under discussion Sunday appeared unlikely to settle other outstanding issues, including the sequester, which would total more than $1 trillion in cuts over 10 years, divided equally between the Defence Department and other government agencies. And off the table completely is an extension of the nation's borrowing limit, which the government is on track to reach any day but which the Treasury can put off through accounting measures for about two months.
That means Obama and the Congress are already on a new collision path. Republicans say they intend to use the debt ceiling as leverage to extract more spending cuts from the president. Obama has been adamant that unlike 2011, when the country came close to defaulting on its debts, he will not yield to those Republican demands.
Lawmakers have until the new Congress convenes to pass any compromise, and even the calendar matters. Democrats said they had been told House Republicans might reject a deal until after Jan. 1, to avoid a vote to raise taxes before they had technically gone up, and then vote to cut taxes after they had risen.
