US stocks dipped, recording their first loss of the week as President Barack Obama and Republicans in Congress sniped at each other and a deadline to avoid sweeping tax increases and government spending cuts drew closer.
General Motors' stock surged after the government announced plans to sell its ownership stake in the company.
The Dow Jones industrial average closed down 98.99 points, or 0.7%, at 13,251.97. The Standard & Poor's 500 index dropped 10.98 points, or 0.8%, to 1,435.81.
The Nasdaq composite index fell 10.17, or 0.3%, to 3,044.36.
Mr Obama said that he and House speaker John Boehner were "pretty close" to a deal to avoid the tax increases and spending cuts, a combination known as the "fiscal cliff". The two sides have exchanged proposals this week.
But the president also said that congressional Republicans keep finding "ways to say no as opposed to finding ways to say yes".
He said the nation deserves compromise in the aftermath of the Connecticut school shooting.
Mr Boehner, speaking to reporters for less than a minute and in a defiant tone, called on Mr Obama to offer a deficit-cutting plan balanced between spending cuts and tax increases.
He predicted that the House of Representatives would pass his back-up plan, which calls for extending decade-old tax cuts for Americans making less than one million dollars a year. The White House has rejected that plan.
The S&P 500 index had gained more than 2% over the previous two days in part because of optimism about a deal taking shape. The optimism seemed to melt today and stocks finished near their lows for the day.
GM soared $1.69, or 6.6%, to 27.18 after the company said it would spend 5.5 billion dollars to buy 200 million shares of its own stock back from the government.
The government pledged to sell the other 300 million GM shares it owns on the open market and shed its entire ownership stake in 12 to 15 months. The government got GM stock as part of a 2009 bailout.
US builders broke ground on fewer homes in November after starting work in October at the fastest pace in four years. Superstorm Sandy probably distorted the totals in the Northeast.

Materials stocks fell just 0.5%, less than the rest of the market. Industrials fell 0.7%. Elsewhere on Wall Street, telecommunications stocks and health care stocks fared the worst, down 1.2% and 1.1% respectively.
