Trump targets Amazon for making Post Office ‘dumber and poorer’

US President Donald Trump has used his Twitter account to take aim at Amazon, calling on the country’s postal service to charge the online retailer more for shipping. 

‘Why is the United States Post Office, which is losing many billions of dollars a year, while charging Amazon and others so little to deliver their packages, making Amazon richer and the Post Office dumber and poorer? Should be charging MUCH MORE!’ Trump tweeted.

This isn’t the first time Trump has picked a fight with Amazon. In August, he tweeted: 'Amazon is doing great damage to tax paying retailers. Towns, cities and states throughout the US are being hurt - many jobs being lost!'
