Congressional negotiators unveiled a mammoth $1.7 trillion funding bill early Tuesday, as leaders scramble to quickly sort out government funding for fiscal 2023 before the end of the month.

The 4,155-page funding package, which lawmakers hope to pass later this week, includes $772.5 billion in non-defense discretionary spending, and $858 billion in defense funding, a figure in line with the dollar level set by the National Defense Authorization Act that passed both chambers earlier this month.

Negotiators say they settled on more than $45 billion in funding to support Ukraine amid Russia’s ongoing invasion, up from the $37.7 billion that the White House requested in assistance last month. 

“Passing this bipartisan, bicameral, omnibus appropriations bill is undoubtedly in the interest of the American people,” Senate Appropriations Chair Patrick Leahy (D-Vt.) said. “It is the product of months of hard work and compromise, and I want to thank my friends Vice Chairman Shelby and Chair DeLauro for their partnership and hard work.”

The package consists of all 12 annual appropriations bills Congress, and would fund the government through the remainder of fiscal 2023, which runs through now until September.

Hours ahead of the package’s unveiling, Senate Republican Leader Mitch McConnell (R-Ky.) boasted the plus-up in proposed defense funding as significant when compared to the smaller increase seen in nondefense funding levels that would be set in the omnibus.

McConnell said the bill would provide “a substantial real-dollar increase to the defense baseline and a substantial real-dollar cut to the non-defense, non-veterans baseline.” He noted that, unlike the proposed defense budget, the nondefense baseline would see an increase below the rate of inflation. 

Negotiators say defense funding baseline saw about a 10 percent increase, compared to almost half that increase for the nondefense baseline, when not factoring the veterans funding – which Democrats had previously pressed be categorized in its own section in spending talks.

By comparison, the annual inflation rate hit 7.1 percent last month.

Republicans pressed hard for domestic spending that Democrats passed in packages without GOP support, like the Inflation Reduction Act and the American Rescue Plan, to also be factored into negotiations, while pressing for a drawdown in nondefense spending.

One of the biggest battles seen in the weeks leading up to the bill brewed within the GOP over how long Congress should delay setting new government funding levels for fiscal 2023, which began in October.

Republicans in both chambers have been pressuring leaders to hold off new government funding until next early year, when the House ushers in a GOP-led majority, to give the party more influence over how agencies should be funded through next fall.

“I object to the way we run our government, the way Congress really abdicates its power of the purse,” Sen. Rand Paul (R-Ky.) said on Monday, lamenting the omnibus as “thousands of pages long created by a few people basically in secret.”

“I object to a trillion deficit being added to our total tab of $31 trillion. So I object to the entire process — to the spending, to the debt being added. How that works out this week I don’t know yet, but I promise you were going to be very loud,” he added.

It’s unclear when the bill will come to the floor, but the Senate is expected to vote on the legislation by Dec. 22.

Its expected passage in the days ahead will cap off months of stalemates and haggling between both sides over issues like levels of growth for defense and nondefense spending and decades-old riders.

However, many Republicans have pushed back on the idea, instead citing concerns about funding for national security and defense. 

Congress currently has until Friday to pass funding legislation to stave off a shutdown.
