The federal government has three days left to raise the nation's current $14.3 trillion debt ceiling, the Treasury Department said. Failure to do so will risk an unprecedented national default.
If the debt ceiling is not raised by Tuesday, Americans could face rising interest rates and a declining dollar, among other problems.
As the cost of borrowing rises, individual mortgages, car loans and student loans could become significantly more expensive. Some financial experts have warned of a downgrade of America's triple-A credit rating and a potential stock market crash.
Without an increase in the debt limit, the federal government will not be able to pay all of its bills next month. President Barack Obama recently indicated he can't guarantee Social Security checks will be mailed out on time. Other critical government programs could be endangered as well.
Where do things stand in the fight to raise the debt ceiling?
Senate Majority Leader Harry Reid, D-Nevada, temporarily stopped legislative consideration of his debt ceiling proposal late Saturday night, reversing an earlier decision to hold a key procedural vote on the measure by 1 a.m. ET Sunday.
Negotiations were still underway at the White House, Reid said. The vote will now be held at 1 p.m. ET on Sunday.
There are "many elements to be finalized" and still "a distance to go," Reid said. "We should give everyone as much room as possible to do their work."
The announcement comes a few hours after Reid denied claims from House Speaker John Boehner, R-Ohio, that progress was being made on a debt ceiling deal.
The Republicans "refuse to negotiate in good faith," Reid said. "The process has not been moved forward during this day."
The Democratic-led Senate on Friday blocked the Boehner plan from being considered, voting 59-41 to table the measure.
Under an amended version, it would reduce federal deficits over the next decade by $2.4 trillion while raising the debt ceiling by a similar amount – meeting the GOP's demand that total savings should at least equal any total debt ceiling hike.
Roughly $1 trillion in the savings are based on the planned U.S. withdrawals from military engagements in Afghanistan and Iraq.
Reid's plan also would establish a congressional committee made up of 12 House and Senate members to consider additional options for debt reduction. The committee's proposals would be guaranteed a Senate vote with no amendments by the end of this year.
In addition, it incorporates a process proposed by Senate Minority Leader Mitch McConnell, R-Kentucky, that would give Obama the authority to raise the debt ceiling in two steps while providing Congress the opportunity to vote its disapproval.
House Speaker John Boehner expressed optimism Saturday that an agreement is near, despite the House's rejection of a plan proposed by Senate Majority Leader Harry Reid.
"In spite of our differences, we're dealing with reasonable, responsible people," Boehner said.
Senate Minority Leader Mitch McConnell, R-Kentucky, also said Saturday afternoon that he had talked to President Barack Obama and Vice President Joe Biden "within the last hour" and is "confident and optimistic" that there will be an "agreement within the very near future."
Earlier Saturday, the Republican-controlled House of Representatives rejected Reid's proposed debt ceiling plan in a sharply polarized 173-246 vote. Republicans unanimously opposed the measure while most Democrats backed it. GOP leaders conducted the vote on Reid's bill under rules requiring a two-thirds majority for passage, thereby ensuring its defeat.
The Republican-controlled House on Friday passed a proposal put forward by House Speaker John Boehner, R-Ohio, that seeks to raise the debt ceiling and cut government spending while requiring that Congress pass a balanced-budget amendment to the U.S. Constitution. The 218-210 vote was strictly on party lines. The vote had been scheduled to occur Thursday night, but Republican leaders postponed it because they lacked support within their own caucus to get it passed. After the House vote, the measure went to the Senate, where Democrats blocked it from being considered.
Boehner's plan calls for $917 billion in savings over the next decade, while creating a special congressional committee to recommend additional savings of $1.6 trillion or more. It would allow the debt ceiling to be increased by a total of roughly $2.5 trillion through two separate votes. The $2.5 trillion total would be enough to fund the federal government through the end of 2012.
The plan originally called for a congressional vote on a balanced-budget amendment to the Constitution by the end of the year. Boehner then reached out to disgruntled conservatives by amending the plan to require congressional passage of such an amendment as a condition for raising the debt limit by the full $2.5 trillion.
Obama has endorsed Reid's plan and threatened a veto of Boehner's plan. The president strongly opposes any bill that doesn't raise the debt ceiling through the 2012 election, and he has promised to veto any short-term debt ceiling extension unless it paves the way for a "grand bargain" of more sweeping reforms and revenue increases.
On Friday, Obama urged Senate Democrats and Republicans to take the lead in congressional negotiations. He said the House GOP plan "has no chance of becoming law." Obama also urged Americans to keep contacting members of Congress in order "to keep the pressure on Washington."
The president made a nationally televised plea for compromise Monday night, though he also criticized Republicans for opposing any tax hikes on the wealthy.
No face-to-face negotiations are currently scheduled for Saturday.
