President Trump called out Amazon CEO and Washington Post owner Jeff Bezos on Twitter, Sunday, referring to the billionaire as “Jeff Bozo” in a post to Twitter.

“So sorry to hear the news about Jeff Bozo being taken down by a competitor whose reporting, I understand, is far more accurate than the reporting in his lobbyist newspaper, the Amazon Washington Post,” President Trump declared. “Hopefully the paper will soon be placed in better & more responsible hands!” Trump was referring to reports in the National Enquirer about Bezos’ alleged affair.

President Trump and Bezos have previously engaged in public spats, going all the way back to Trump’s 2016 election campaign, and in June, Trump encouraged Washington Post employees to go on strike against Bezos.

Washington Post employees want to go on strike because Bezos isn’t paying them enough. I think a really long strike would be a great idea. Employees would get more money and we would get rid of Fake News for an extended period of time! Is @WaPo a registered lobbyist? — Donald J. Trump (@realDonaldTrump) June 17, 2018

On Saturday, President Trump accused the Washington Post of being a “lobbyist” newspaper for Amazon.

“Washington Post, that’s basically the lobbyist for Amazon. You know, he uses that — Bezos has got bigger problems than anybody right now. But Bezos uses that as his lobbyist, OK, as far as I’m concerned,” Trump claimed. “And The Washington Post is almost as bad or probably as bad as The New York Times.”

In March, shares in Amazon dropped after it was revealed that President Trump “hates” the company, and the president has repeatedly referred to the Washington Post as the “Amazon Washington Post,” and “fake news.”

The Amazon Washington Post fabricated the facts on my ending massive, dangerous, and wasteful payments to Syrian rebels fighting Assad….. — Donald J. Trump (@realDonaldTrump) July 25, 2017

Is Fake News Washington Post being used as a lobbyist weapon against Congress to keep Politicians from looking into Amazon no-tax monopoly? — Donald J. Trump (@realDonaldTrump) July 25, 2017

It's hard to read the Failing New York Times or the Amazon Washington Post because every story/opinion, even if should be positive, is bad! — Donald J. Trump (@realDonaldTrump) July 23, 2017

“Amazon is doing great damage to tax paying retailers. Towns, cities and states throughout the U.S. are being hurt – many jobs being lost!” posted President Trump in August 2017, adding in December, “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!”

In March 2018, he went after Amazon again, posting, “I have stated my concerns with Amazon long before the Election. Unlike others, they pay little or no taxes to state & local governments, use our Postal System as their Delivery Boy (causing tremendous loss to the U.S.), and are putting many thousands of retailers out of business!”

I am right about Amazon costing the United States Post Office massive amounts of money for being their Delivery Boy. Amazon should pay these costs (plus) and not have them bourne by the American Taxpayer. Many billions of dollars. P.O. leaders don’t have a clue (or do they?)! — Donald J.

Bezos criticized President Trump’s comments about the Washington Post in September, proclaiming, “it’s really dangerous to demonize the media.”
