Senate Republican Leader Mitch McConnell of Kentucky and Senate Democratic Leader Charles Schumer of NY have both championed the agreement as a bipartisan breakthrough that would end the destabilizing cycle of short-term spending bills that lawmakers have had to pass repeatedly to keep the lights on at government agencies.
Senate Minority Leader Charles E. Schumer, D-N.Y., touted many Democratic priorities, including a two-year extension of funding for community health centers, a 10-year extension of funding for the Children's Health Insurance Program and money to fight the opioid drug crisis.
Senate Majority Leader Mitch McConnell, R-Ky., filed a motion to end debate on the budget deal late Wednesday night.
The deal, if approved, would also fund the federal government until March 23, averting a second shutdown this year and giving lawmakers six weeks to resolve their differences over immigration policy and write the full-year budget. The House bill is not anticipated to pass the Senate.
More funding for disaster relief: The plan includes $90 billion more to be spent on disaster aid for recent hurricanes and wildfires, which have spurred calls from some lawmakers for a more robust federal response. McConnell's bill fails to hit the numbers set by the President, which aimed at a $52 billion increase to defense spending from the 2017 budget.
The bill is expected to pass the Senate without much difficulty, before facing a harder sell in the House of Representatives.
While the Republican side of the chamber was largely empty, many Democrats sat behind their leader offering support.
And liberal stalwarts including top House Democrat Nancy Pelosi were also in revolt, because the deal does nothing to protect young undocumented immigrants from deportation.
"I think it's very important for DACA that there be a significant presence of votes against whatever comes over, and not just for DACA, there's other reasons (to oppose the deal)", said Rep. Raul Grijalva, an Arizona Democrat and Hispanic caucus member.
Pelosi filibustered House business for over eight hours with a marathon floor speech demanding a vote on DACA.
"Work on immigration is one thing, we've been working on immigration for a long time", Curbelo said.
In addition, it would set aside $6 billion for funding opioid and mental health programs, including prevention and treatment initiatives.
Suspends the debt ceiling until March 1, 2019.
On Tuesday, Trump injected uncertainty into the funding debate when he said he would "love" to see a shutdown if Democrats do not back his immigration demands.
"According to Politico, Pelosi said she will not be voting for the bill: "'I'm pleased with the product, I'm not pleased with the process, ' Pelosi told reporters Thursday, later adding she plans to vote against the bill but confirmed she isn't formally whipping against it.
House Speaker Paul Ryan (R-Wis.) has said that President Donald Trump's support is a must for any immigration reform bill to move forward and that the lower chamber will address DACA separately from appropriations.
By Thursday evening, the White House was preparing for a lapse in appropriations.
One complication is House Minority Leader Nancy Pelosi of California, who was part of the negotiations on the agreement.
Dreamers, the immigrants who came to the US illegally as children, risk deportation with the expiration of DACA, which has allowed them to apply to live and work here.
But apart from the short-term implications, the two-year deal reached by senators, if backed by the House, may be a source of wider concern.
