Senate Democrats emerged from a two-and-a-half-hour caucus meeting Sunday night announcing there will be enough votes in the Senate to reopen the federal government after a grueling 40-day shutdown.

A group of centrist Democrats led by Sens. Angus King (Maine), an independent who caucuses with Democrats, and Jeanne Shaheen (D-N.H.). and Maggie Hassan (D-N.H.), negotiated the deal to reopen government with Republicans on the Senate Appropriations Committee led by Sen. Susan Collins (R-Maine) and the Senate GOP leadership.

Collins led the negotiations on a minibus appropriations package to fund military construction, veterans affairs, the Department of Agriculture and the legislative branch as well as a continuing resolution to fund the government until Jan. 30.

Shaheen, a member of the Appropriations Committee, worked with Collins on the funding bills.

King and Hassan played a key role in getting Senate Majority Leader John Thune (R-S.D.) to promise a vote this year on extending enhanced health insurance subsidies under the Affordable Care Act (ACA) that are due to expire at the end of the year.

King told reporters after the Democratic caucus meeting that there will be the votes to pass the deal through the Senate and that the Democrats who are backing the legislation feel the shutdown has gone on long enough.

Asked if he`s confident there would be enough votes to pass the bill, King told reporters: "That`s certainly what it looks like."

The Senate will go back into session at 8 p.m. Sunday and is expected to vote Sunday evening to end the shutdown.

King said "the length of the shutdown" persuaded Democrats to support the deal, many elements of which had been on the negotiating table for weeks.

He said it became increasingly clear that Republicans were not going to agree to a deal to reopen the government and extend enhanced health insurance subsidies under the Affordable Care Act that are due to expire in January.

King says there`s still a "chance" the subsidies will be renewed because Thune has promised as part of the deal to give Democrats a vote on the ACA subsidies in November.

"Part of the deal is a vote on the ACA subsidies," he said.

He said that he and other members of the Democratic caucus want to end the shutdown in the next few days because "a lot of people are being hurt."

The bill still needs to pass the House, which hasn`t voted since Sept. 19. It then needs to go President Trump`s desk for a signature.

Several Democrats emerged from the meeting, however, pledging to oppose the deal, including Sens. Richard Blumenthal (D-Conn.), Ruben Gallego (D-Ariz.), Tammy Baldwin (D-Wis.) and Chris Van Hollen (D-Md.).

"A wink and a nod to deal with this health care crisis later - with no actual guarantees - is just not enough for me or the Wisconsin families I work for," Baldwin said in a statement.

If it passes, it would then head to the House, which has been on recess since September. And it is not clear that the deal has the support of House Democrats.

The agreement drew mixed early reaction from Senate Democrats.

"Because of Republicans, Americans are going to suffer immensely as this health care crisis gets worse," Senate Minority Leader Chuck Schumer, D-N.Y., said before the vote, slamming Republicans for repeatedly refusing Democratic proposals to continue the ACA funds. "Therefore, I must vote no."

Sen. Ruben Gallego, D-Ariz., said he`ll oppose the deal, as it fails to extend the ACA tax credits.

"I have been clear on this from the beginning: I will not turn my back on the 24 million Americans who will see their premiums more than double if we don`t extend these tax credits," he said.

Sen. Tim Kaine, D-Va., said he will vote for it. "I have long said that to earn my vote, we need to be on a path toward fixing Republicans` health care mess and to protect the federal workforce," said Kaine. "This deal guarantees a vote to extend Affordable Care Act premium tax credits, which Republicans weren`t willing to do. Lawmakers know their constituents expect them to vote for it, and if they don`t, they could very well be replaced at the ballot box by someone who will."
