A $1.2 trillion infrastructure bill cleared a procedural hurdle Sunday, setting up a final vote by Tuesday or sooner on a measure President Joe Biden and Democrats hope to tout as a major bipartisan achievement that will create jobs and provide much-needed funding for roads, bridges, water projects, and broadband access.

The Senate convened for a rare Sunday session that cut into their scheduled August recess, haggling all day about a package of amendments without reaching a deal. Democrats are counting on the bill to help pave the way for the passage later this year of a much larger spending package that would fund a broad array of social programs.

Lawmakers voted to cut off debate on Sunday evening, setting up another clock that runs out on Tuesday, when the Senate will be able to take a final vote on the bill.

The measure provides $550 billion in new spending, including $7.5 billion on new electric vehicle charging stations as well as billions on mass transit and rail.

A group of Senate Democrats, Republicans, and Biden negotiated the deal, however, it never won favor with a majority of GOP lawmakers, who opposed the cost and lack of offsets.

The Congressional Budget Office confirmed their skepticism last week with a report showing only half of the new spending would be offset by provisions in the bill and the rest would add to the deficit. Many Republicans raised objections to the measure, and the Senate defeated a move by Oklahoma Rep. James Lankford to block the bill because it was not properly vetted through his committee.

“I’ve been told over and over again that the infrastructure package would be paid for,” Lankford said. “Then I was told, it would be mostly paid for, and then the CBO came out a couple of days ago and said a quarter of a trillion dollars of it is not paid for.”

Lankford also criticized a provision that would raise funding by selling off some of the nation’s strategic oil reserves, which he noted would be used to pay for electric vehicle charging stations.

Lawmakers hoped to strike a deal on a set of amendments that would include provisions sought by both parties. Senators have negotiated language for an amendment that would address taxing cryptocurrency and another amendment that would allow states to spend some unused federal COVID aid on infrastructure.

While lawmakers are still negotiating votes on amendments, the bill is on track to easily pass by Tuesday.

“Republicans and Democrats agree that roads, bridges, broadband, ports, and rail are the building blocks of a healthy economy,” said Sen. Roger Wicker, a Mississippi Republican, who was among the negotiators. “This bill makes historic down payments on those core priorities.”

The Senate will begin debating a budget resolution later this week that unlocks the ability of Senate Democrats to pass a $3.5 trillion social spending package later in the year without any Republican support. Democrats are linking together the bipartisan infrastructure bill and the $3.5 trillion measure, which they labeled a “human infrastructure” bill. The legislation would pay for universal preschool, free community college, broader access to Medicare, and more.

“This mammoth $1.2 trillion infrastructure bill is the runway to Biden’s $3.5 trillion spending spree,” Sen. Ted Cruz, a Texas Republican who voted against advancing the infrastructure package, said Sunday.

Eighteen Republicans voted to advance the bipartisan infrastructure legislation in spite of the second, bigger spending bill looming in the weeks again that they will not have the power to block.

Republican senators praised the funding provisions in the bipartisan bill that would help their states fix infrastructure, replace aging water pipes and expand internet access.

“Tonight is the real infrastructure deal that America needs,” Wicker said.
