New York - Wall Street stocks tumbled precipitously just before midday on Tuesday after Donald Trump Jr released emails showing he embraced Russia's efforts to support his father's presidential campaign.
US stocks had been flat to positive prior to the revelations released on Twitter, which revived worries that President Donald Trump's Russia travails could derail his agenda.
The Dow Jones Industrial Average fell as far as 0.6% immediately after the news broke, but by 15:45 GMT, was down 0.3% at 21 341.18.
The broad-based S&P 500 also dropped 0.3% to 2 420.18, while the tech-rich Nasdaq Composite Index lost less than 0.1% at 6 174.07.
Trump junior was told by an interlocutor that he could get "very high level and sensitive information" that was "part of Russia and its government's support for Mr. Trump".
The revelations come amid ongoing probes of the Trump campaign's connections to Russians. They also raise questions about the string of denials from Trump and his team that the campaign colluded with Russian government hackers whom US officials have blamed for attacks on Democratic presidential candidate Hillary Clinton.
US stocks had earlier been in a holding pattern ahead of congressional testimony on Wednesday from Federal Reserve Chair Janet Yellen.
Analysts have seen lofty stock valuations as a challenge for further appreciation in equities, and the news on Tuesday gave an incentive to profit taking.
