"The speaker the day after the election said we would give on taxes and we have. But we wanted spending cuts. This bill has spending increases. Are you kidding me? So we get tax increases and spending increases? Come on."
Cantor told reporters at one point, "I do not support the bill. We are looking, though, for the best path forward."
Within hours, Republicans abandoned demands for changes and agreed to a simple yes-or-no vote on the Senate-passed bill.
They feared that otherwise the Senate would refuse to consider any alterations, sending the bill into limbo and saddling Republicans with the blame for a whopping middle class tax increase. One Senate Democratic leadership aide said Majority Leader Harry Reid would "absolutely not take up the bill" if the House changed it. The aide spoke on condition of anonymity, citing a requirement to keep internal deliberations private.
Despite Cantor's remarks, Boehner took no public position in advance of voting the bill as he sought to negotiate a conclusion to the final crisis of a two-year term full of them.
The brief insurrection wasn't the first time that the tea party-infused House Republican majority has rebelled against the party establishment since the GOP took control of the chamber 24 months ago. But with the two-year term set to end Thursday at noon, it was likely the last. And as was true in earlier cases of a threatened default and government shutdown, the brinkmanship came on a matter of economic urgency, leaving the party open to a public backlash if tax increases do take effect on tens of millions.
The non-partisan Congressional Budget Office said the measure would add nearly $4 trillion over a decade to federal deficits, a calculation that assumed taxes would otherwise have risen on taxpayers at all income levels. There was little or no evident concern among Republicans on that point, presumably because of their belief that tax cuts pay for themselves by expanding economic growth and do not cause deficits to rise.
The relative paucity of spending cuts was a sticking point with many House Republicans. Among other items, the extension of unemployment benefits costs $30 billion, and is not offset by savings elsewhere.
Others said unhappiness over spending outweighed fears that the financial markets would plunge on Wednesday if the fiscal cliff hadn't been averted.
"There's a concern about the markets, but there's a bigger concern, which is getting this right, which is something we haven't been very good at over the past two years," said Rep. Steve LaTourette of Ohio.
For all the struggle involved in the legislation, even its passage merely cleared the way for another round of controversy almost as soon as the new Congress convenes.
With the Treasury expected to need an expansion in borrowing authority by early spring, and funding authority for most government programs set to expire in late March, Republicans have made it clear they intend to use those events as leverage with the administration to win savings from Medicare and other government benefit programs.
McConnell said as much moments before the 2 a.m. Tuesday vote in the Senate — two hours after the advertised "cliff" deadline.
"We've taken care of the revenue side of this debate. Now it's time to get serious about reducing Washington's out-of-control spending," he said. "That's a debate the American people want. It's the debate we'll have next. And it's a debate Republicans are ready for."
Obama addressed the same point in his brief remarks. He said he is prepared to take steps to control spending this year, and noted pointedly that savings must be found in Medicare. "I believe that there's further unnecessary spending in government that we can eliminate," he said.
Countering McConnell and other Republicans, the president said future legislation must combine additional revenues and spending cuts, and he warned the GOP not to try and use the expiration of the Treasury's borrowing authority to force spending cuts.
The 89-8 vote in the Senate was unexpectedly lopsided.
Despite grumbling from liberals that Obama had given way too much in the bargaining, only three Democrats opposed the measure.
Among the Republican supporters were Sen. Pat Toomey of Pennsylvania, an ardent opponent of tax increases, as well as Sen. Ron Johnson of Wisconsin, elected to his seat two years ago with tea party support.
