Wall Street turned lower as a rise in tensions in Washington threatened to unravel significant progress made over the last week in talks that aim to slow the growth of the country's $16 trillion debt.
President Barack Obama accused Republicans of digging in their heels due to a personal grudge against him while the Republican speaker of the House of Representatives, John Boehner, called Obama "irrational."

Equity markets in Europe rose as a key business survey in Germany bolstered investor sentiment by suggesting that Germany, Europe's biggest economy, was likely to bounce back quickly from a slowdown.

Investors gave little importance to data that showed U.S. homebuilding permits touched their highest level in nearly 4-1/2 years in November, while ground-breaking activity dropped. The rise in building permits was led by a 10.6 percent gain in permits for multi-family homes, offsetting a 0.2 percent slip in permits for single-family homes.
In Europe, top company shares scaled 18-month highs on expectations the U.S. fiscal debacle will be averted.
The FTSEurofirst 300 index rose 0.41 percent to end at 1,142.13, just off a 19-month closing high.
The better tone in global markets was supported by the U.S. Federal Reserve's efforts to boost the U.S. recovery, signs of growing economic momentum in China, and talk that Japan is set for a policy shift to lift itself out of recession.
The latest German Ifo Institute survey of 7,000 firms bolstered this sentiment by finding that business confidence had improved for a second straight month in December, in part because of better export prospects.
