From the Wall Street Journal: Why Trump is trashing Amazon (and how much it hurts)

U.S. president Donald Trump is a long-time Amazon critic. Lately, however, he has been tweeting up a storm about the online retail giant. Trump has criticised Amazon's relationship with the U.S. Postal Service and has complained that the company doesn't pay sales tax (it does in states that require it to). The Amazon share price has fallen in response to the attacks as investors worry about potential regulation or changes to Amazon's delivery costs. This podcast takes a look at the Trump vs Amazon fight.
