Stocks sink after Democrats say they'll forge ahead with impeachment inquiry

Stocks fell Tuesday after Rep. John Lewis said he is in favor of moving forward with an impeachment inquiry against President Trump for his asking of Ukrainian President Volodymyr Zelensky to investigate former Vice President Joe Biden and his son.

House Speaker Nancy Pelosi announced a formal impeachment inquiry on Tuesday after the close of trading. Trump responded with the tweet: "PRESIDENTIAL HARASSMENT!"

The major averages closed lower following Lewis', D-Ga., comments but pared their losses after Trump tweeted he would release the unredacted Ukraine transcript in full.

The Dow Jones Industrial Average finished down 142.22 points, or 0.53 percent. The S&P 500 and Nasdaq fell 0.84 percent and 1.46 percent, respectively.

Stocks were already under pressure following the release of disappointing U.S. economic data and President Trump's speech to the United Nations in which he called out China.

"Not only has China declined to adopt promise reforms, it has embraced an economic model dependent on massive market barriers, heavy state subsidies, currency manipulation, product dumping, forced technology transfers and the theft of IP, and trade secrets on a grand scale,” the president said during his 30-minute speech.

Earlier Tuesday, the Conference Board said that the consumer confidence index fell from 134.2 in August to 125.1 this month, its weakest reading in three months. The S&P Case-Shiller home index said prices rose 2 percent in July, their slowest appreciation since 2012.
