Officials said Democrats had failed in their bid to include an extension of benefits for workers unemployed longer than 26 weeks. The program expires on Dec. 28, when payments will be cut off for an estimated 1.3 million individuals.
Announcement of the deal came in the form of a statement that the two negotiators, Sen. Patty Murray, D-Wash., and Rep. Paul Ryan, R-Wis., who planned a news conference to announce details. The lawmakers chair the budget committees in the two houses of Congress, and negotiated the deal in secretive talks over recent weeks.
Officials said that under the agreement, an estimated $65 billion in automatic spending cuts would be restored through the end of the next budget year, which runs to Sept. 30, 2015.
Officials who described the details in advance of the news conference did so on the condition of anonymity, saying they were not authorized to speak on the record.
The same was not true of conservative organizations, which attacked the proposal as a betrayal of a hard-won 2011 agreement that reduced government spending and is counted as among the main accomplishments of tea party-aligned Republicans who came to power earlier the same year in the House.
Americans for Prosperity issued a midmorning statement saying that GOP lawmakers should uphold current spending levels. Otherwise, the group said, "congressional Republicans are joining liberal Democrats in breaking their word to the American people to finally begin reining in government overspending that has left us over $17 trillion in debt."
A day earlier, Heritage Action issued a similar broadside, saying it could not support a deal that "would increase spending in the near-term for promises of woefully inadequate long-term reductions." The group played an influential behind-the-scenes role earlier this fall in events that led to a partial government shutdown, supporting a strategy of refusing to provide needed funds for federal programs until the health care law known as "Obamacare" was defunded.
For their part, liberals were unhappy that the deal was likely to lack an extension of benefits for unemployed workers more than 26 weeks off the job.
The party's leader, Rep. Nancy Pelosi of California, said at one point last week that her rank and file would insist on an extension for the unemployment program as a condition for supporting a budget deal.
The White House pointedly refused to support her position, and she later made additional comments that her staff characterized as a clarification.
Given the internal GOP divisions in the House, Speaker John Boehner is likely to need Democratic votes to approve any deal by Ryan and Murray. It was not immediately clear how many Democratic lawmakers would support a plan that lacked an extension of unemployment benefits.
Some Democratic officials suggested a possible two-step solution. It included swift passage of any budget agreement that emerges, and then adding an extension of unemployment benefits to must-pass legislation early next year, perhaps a measure to reverse a looming cut in payments to doctors who treat Medicare patients.
The bipartisan push for a budget agreement stems from automatic cuts that are themselves the consequence of divided government's ability to complete a sweeping deficit reduction package in 2011.
If left in place, the reductions would carve $91 billion from the day-to-day budgets of the Pentagon and domestic agencies when compared with spending limits set by the hard-fought 2011 budget agreement.
Support for a deal to ease the reductions is strongest in Congress among defense hawks in both houses and both parties who fear the impact on military readiness from a looming $20 billion cut in Pentagon spending.
