“I’m sure of one thing: It’s going to be enormous,” the West Virginia Democrat, who is seen as a swing vote in a chamber divided 50-50, told reporters at the Capitol.

While he didn’t predict a price tag, Manchin said Congress should do “everything we possibly can” to pay for it. He said there should be “tax adjustments” to former President Donald Trump’s 2017 tax law to boost revenues, including by raising the corporate rate from the current 21 percent to at least 25 percent.

Some of the tax benefits in the Republican law were “weighted in one direction” and could be reversed, Manchin said. He also suggested an “infrastructure bank” paid for with revenues, potentially a value-added tax, that would be used for “rebuilding America.”
