"This is clearly Washington-driven," said Michael Shaoul, chairman and CEO of Marketfield Asset Management. "It's a lot like 1998-99, when the market had to deal with the [Monica] Lewinsky scandal."
The Dow Jones industrial average ended about 370 points lower, with Goldman Sachs contributing the most losses. The S&P 500 dropped 1.8 percent, with financials tumbling 3.1 percent to lead decliners.
