House Speaker John Boehner couldn't hold back when he spotted Senate Majority Leader Harry Reid in the White House lobby last Friday.
It was only a few days before the nation would go over the fiscal cliff, no bipartisan agreement was in sight, and Reid had just publicly accused Boehner of running a "dictatorship" in the House and caring more about holding onto his gavel than striking a deal.
"Go f-- yourself," Boehner sniped as he pointed his finger at Reid, according to multiple sources present.
Reid, a bit startled, replied: "What are you talking about?"
Boehner repeated: "Go f-- yourself."
The harsh exchange just a few steps from the Oval Office -- which Boehner later bragged about to fellow Republicans -- was only one episode in nearly two months of high-stakes negotiations laced with distrust, miscommunication, false starts and yelling matches as Washington struggled to ward off $500 billion in tax hikes and spending cuts.
The White House and Congress knew of the self-imposed deadline for more than 17 months and they still blew past it, as a president fresh off a strong reelection victory tested -- and ultimately broke -- the Republican Party's fidelity to its tax-cuts-only governing philosophy.
It took a late intervention of two Senate veterans -- Senate Minority Leader Mitch McConnell (R-Ky.) and Vice President Joe Biden -- to rescue the negotiations. Their relationship, forged over two decades on Capitol Hill, helped move Congress to a resolution because it wasn't burdened by the raw political conflicts of the past and the legislative fights still to come.
