U.S. stocks swung lower on Tuesday after President Donald Trump’s eldest son released an email chain, which referred to a top Russian government prosecutor as offering the Trump campaign damaging information about Democratic rival Hillary Clinton.
“The Crown prosecutor of Russia … offered to provide the Trump campaign with some official documents and information that would incriminate Hillary and her dealings with Russia and would be very useful to your father,” said the June 3, 2016, email to Donald Trump Jr. from publicist Rob Goldstone.
Trump’s son, Donald Trump Jr., agreed to meet with a Kremlin-linked lawyer during the 2016 election campaign after being promised damaging information about Hillary Clinton, the New York Times reported on Sunday.
“I think people are worried that it just means more political uncertainty, and sort of a continuation of the stalemate in Washington, a continuation of the delay in trying to get the Trump agenda passed through Congress,” said Robert Pavlik, chief market strategist at Boston Private Wealth in New York.
