Trump continues bashing Amazon

Trump's bashing of Amazon continues on Twitter. 4 times in the last week now. His latest tweet, sticks with the argument 'that Amazon is costing the United States Postal Service massive amounts of money for being their delivery boy'. --Reports late in the day that the WH wasn't holding any Amazon discussions led to a bit of an amazon rally. are we going to be hanging onto Trump's every tweet? ---It doesn't look like the President is going to stop sharing his dislike for Amazon on Twitter. But are investors going to continue to listen?
