At least eight centrist Democratic senators have reached a tentative agreement with Republican leaders in the Senate and the White House to reopen the government.
The deal covers funding government operations through January 30 and will be voted on by the Senate, then the House of Representatives, before being sent to the President's desk for signature and reopening.
The move comes after a government shutdown that has entered its 40th day, leaving scores of federal workers without pay and disrupting many government services.
However, the plan does not include a guarantee that the Health Insurance Contributions Act (ACA) would be extended, a key issue that has previously blocked an agreement.
But Republicans have agreed to call a vote on the subsidies by mid-December.
Key aspects of the deal include guaranteeing back pay for government workers, preventing mass layoffs during the shutdown and funding key agencies until the budget is fully approved.
The agreement still needs to gain enough support in the Senate and then pass through the House of Representatives, with the bill process likely to take several days before the government is actually fully opened.
