Escalation of Trade Tensions

The market opened weaker as the White House announced an escalation of trade tensions between the US and China.  The new story was that the US would/may raise the current $50 billion trade tariffs by an additional $100 billion.

Would the Chinese reciprocate with the same number?  Was it a bluff by the White House?

Despite the market rally in the first 30 min of the day, it remained weak, and then got worse.  The slide made a second run lower when the Fed Chairman did NOT include in his prepared speech that he would do his best impersonation of Ben Bernanke or Janet Yellen: save the market because it was down.

At one point, the Dow was down nearly -800 points.
