Congress has just over a week to meet House Speaker Nancy Pelosi‘s tentative October 31 deadline to pass the $1.2 trillion bipartisan infrastructure bill, which progressives have refused to vote for unless it’s passed in tandem with the larger spending bill.

Manchin expressed doubt about meeting the deadline on Thursday. “This is not going to happen anytime soon,” he told CNN. “They’re trying to get a meeting of minds to find out what can happen from there.”

Among the major investments, the “hard infrastructure” bill includes funding for roads and highways, bridges, broadband development, water support, and airport projects. The “human” spending bill provides funding to fight climate change, expand public housing and health care, among other provisions.

But with moderates and progressives in disagreement over the size, scope and priorities of the package, it’s still unclear what will and won’t be in the final version of the bill.

Progressives, including Sanders and Representative Pramila Jayapal, met with Manchin this week to slowly piece together a framework for the measure. Initially the price tag was set at $3.5 trillion, but that’s likely to be scaled-down to somewhere between $1.9 and $2.2 trillion.

Negotiations hinge on making enough cuts to get Manchin and Sinema onboard with the package, while also ensuring enough progressive priorities are maintained.

Manchin wants to dilute Medicare expansion, the climate provisions and means-test benefits to keep costs down, while Sinema opposes lowering prescription drug prices and the bill’s new tax provisions, which would cover its cost.
