The Senate was on track Sunday night to pass a deal that could end the federal government shutdown, which began on Oct. 1.
A person familiar with the deal told CNBC that enough Democratic senators had agreed to vote for the deal to clear a 60-vote minimum threshold. It would fund the U.S. government through the end of January.
The person familiar with the deal said that there are at least eight members of the Democratic caucus who would vote in favor of it. That would give the measure 61 votes, one more than the minimum required to pass.
If passed, the deal would have to be approved by the House of Representatives and signed into law before the shutdown would end.
The Senate has been stalemated for weeks over the Republican majority's insistence on passing a House bill that would provide short-term funding for government operations, without addressing a key looming question over the fate of enhanced Affordable Care Act tax credits.
