NEW YORK (CNNMoney) -- The Dow dropped 350 points and swung wildly on a report that Michael Flynn is prepared to testify against President Trump.

The sharp slide in the stock market came within minutes of an ABC News report that Flynn is prepared to testify that Trump directed him to make contact with Russians.

CNN has not confirmed the ABC report.

Flynn, Trump's former national security adviser, is expected to plead guilty on Friday to charges he lied to the FBI about conversations with Russia's ambassador, according to court documents.

The Dow was recently down 175 points, while the S&P 500 fell almost 1%. The Nasdaq was down 1.3%.

"This is how a market reacts when there is a large unknown. Everyone wants to know: What's the next shoe to drop?" said Art Hogan, chief market strategist at Wunderlich Securities.

The selloff reflects fears that the Russia scandal will imperil Trump's economic agenda, especially tax cuts. The Flynn charges come just as the Senate is debating a bill to slash corporate tax rates.

The GOP tax plan has helped send U.S. stocks soaring in recent weeks. The Dow spiked 332 points on Thursday and closed above the 24,000 level for the first time.
