Sen. Joe Manchin on Wednesday morning said he has “serious concerns” about his party’s massive $3.5 trillion spending plan, signaling that he may intend to block much of the package supported by President Biden over inflation and debt concerns.

“Early this morning, I voted ‘YES’ on a procedural vote to move forward on the budget reconciliation process because I believe it is important to discuss the fiscal policy future of this country,” Manchin, D-W.Va., said in a statement. “Manchin has ‘serious concerns’ about Dems’ $3.5T spending plan, signaling trouble for Biden agenda.”

Manchin is not the first moderate Democrat to express qualms about the massive spending plan that is being championed by Senate Budget Committee Chairman Bernie Sanders, I-Vt. Sen. Kyrsten Sinema, D-Ariz., said last month, “while I will support beginning this process [of budget reconciliation], I do not support a bill that costs $3.5 trillion.”

But the timing of Manchin’s statement and the fact there are now two Democrats expressing at least some level of opposition to the massive spending, signals that the final bill could need to be significantly pared back to get the votes of the two stalwart moderates. Even that could cause trouble for Democrats, however – it’s not certain progressives in the House or Senate will accept a reconciliation bill that’s meaningfully downsized.

Manchin went on Wednesday to warn of the potential consequences of such massive congressional spending.

“Over the past year, Congress has injected more than $5 trillion of stimulus into the American economy – more than any time since World War II – to respond to the pandemic. The challenge we now face is different: millions of jobs remain unfilled across the country and rising inflation rates are now an unavoidable tax on the wages and income of every American,” he said. “These are not indications of an economy that requires trillions in additional spending.”

“Adding trillions of dollars more to nearly $29 trillion of national debt, without any consideration of the negative effects on our children and grandchildren, is one of those decisions that has become far too easy in Washington,” Manchin added. “Given the current state of the economic recovery, it is simply irresponsible to continue spending at levels more suited to respond to a Great Depression or Great Recession – not an economy that is on the verge of overheating.”
