But by Sunday night, nothing was announced. Both sides are up against an Oct. 17 deadline by which the government will have no more room to borrow. The Treasury Department says it will not have enough money to pay all of the government's bills on that date, which could lead to delays in military pay or Social Security payments — some Democrats have said it would cause the U.S. to default on its debts.

But some Republicans have maintained there is no threat of default, and said the government would only have to ensure it makes interest payments on the debt in order to avoid a default.

As the talks continue, each chamber has a light day of work that could be peppered with floor discussion about the negotiations.

The House starts at noon, and after initial speeches, members will try to finish work on an appropriations resolution that funds the Bureau of Indian Affairs. That resolution is H.J.Res. 80, the American Indian and Alaska Native, Health, Education and Safety Act.

On Saturday, Republicans decided to delay a vote on this measure in order to stop dozens of Democrats from protesting the GOP's decision not to vote on the Senate's clean continuing resolution. Democrats could decide to resume that protest today.

If a roll-call vote is needed, it will take place at 6:30 p.m.

The Senate starts at 2 p.m., and only has judicial nomination votes planned for 5:30 p.m. They are Andrea Wood, who will be a U.S. district judge for Illinois, and Madeleine Hikkela, who will be a U.S. district judge for Alabama.
