Bezos wrote that the publisher had been threatening him with the publication of explicit photos he'd taken of himself unless he stopped investigating who was leaking his photos and texts to the tabloid.
AMI also demanded that Bezos no longer claim the publisher's investigation into his personal life was influenced by political motivations, Bezos wrote.
As a result, Bezos published the emails he'd received from AMI.
"Rather than capitulate to extortion and blackmail, I've decided to publish exactly what they sent me, despite the personal cost and embarrassment they threaten," Bezos wrote.
Bezos also hinted in the post that there may have been a link between the investigation into his relationship with Sanchez and the Saudi Arabian government — specifically, that he might have been a target of the Saudis because he owns the Washington Post, which provided "unrelenting coverage," Bezos said, of the murder of its journalist, Jamal Khashoggi, who was killed by Saudi agents. The "Saudi angle" of Bezos' own investigation into the leaks seemed to have "hit a particularly sensitive nerve" with Pecker, Bezos wrote.
For its part, the Saudi Arabian government denied any role in the situation and called the whole saga a "soap opera."
