President Donald Trump made light of a sharply declining stock market on Friday by blaming it on a Democratic congressman who quit the presidential race earlier in the day.

'The Dow is down 573 points perhaps on the news that Representative Seth Moulton, whoever that may be, has dropped out of the 2020 Presidential Race!' Trump tweeted.

Seconds later, Moulton responded.

“I’m glad he thinks that I have more influence over Wall Street than he does,' he told reporters as he prepared to formally announce to DNC members in San Francisco his departure from the race. 'He’s probably thrilled that I’m out.”

Market watchers said it was Trump’s previous tweet — in which he purported to order U.S. companies to leave China after Beijing’s retaliatory tariffs — that escalated trade fears and led to the sell-off.
