Donald Trump has decided to renew his spat with Jeff Bezos' biggest companies after The Washington Post called him out for trying to quietly link President Obama to this weekend's devastating attack in Orlando.

Trump, the Republican Party's presumptive nominee for President, has now revoked the Post's press access, making it harder for the paper to cover his campaign. His campaign justified this in a statement by describing the Post as Amazon's political mouthpiece "so that they don't have to pay taxes and don't get sued for monopolistic tendencies."

Trump has been complaining about the Post for months

Amazon and The Washington Post are separate companies, but share Bezos' involvement. The Post has been publishing news since 1877.

Trump has been griping about the Post for months now, and today's actions are just his latest attempt at avoiding criticism — or, really, even straight reporting. He was particularly incensed by a Post headline that originally read, "Donald Trump suggests President Obama was involved with Orlando shooting" (it has since been changed to "Donald Trump seems to connect President Obama to Orlando shooting"). Trump's campaign basically called the headline clickbait, although it's a completely fair characterization of his remarks.

Several other news organizations have been rejected from all Trump campaign events or had reporters turned away from individual events. Gawker, which has also had reporters denied credentials, is keeping a list: it includes Univision, BuzzFeed, The Huffington Post, and The National Review.

Trump has been attacking Bezos and his companies for a few months now. In May, Trump made similar comments, again writing off the Post's reporting on him with an unsubstantiated claim that it was doing Bezos' bidding so that he wouldn't get elected and go after Amazon. "He's got a huge antitrust problem," Trump said during an interview with Sean Hannity. "I'll tell you what, we can't let him get away with it."

Amazon declined to comment on this latest attack. Last time, Bezos characterized Trump's remarks as "not an appropriate way for a presidential candidate to behave."
