President Trump railed against Amazon on Wednesday, accusing the mega online retailer of hurting “tax paying retailers.”

“Amazon is doing great damage to tax paying retailers​​,” he wrote on Twitter.​ ​”Towns, cities and states throughout the U.S. are being hurt – many jobs being lost!​”​

Amazon has been a target of Trump’s ire before.

Jeff Bezos, the e-commerce giant’s founder, also owns the Washington Post, which has been ​critical of Trump.

​”​The #AmazonWashingtonPost, sometimes referred to as the guardian of Amazon not paying internet taxes (which they should) is FAKE NEWS!​,” Trump wrote in June.​

It’s unclear what Trump meant about Amazon, since it has been collecting state sales taxes since April.

​And earlier this month, Amazon said that it intends to add 100,000 full-time jobs by the middle of next year.
