The plot is a bit complicated, but here goes. Jamal Khashoggi was a Saudi journalist writing critical stories about the Saudi government. The Washington Post published his stories. Jeff Bezos owns the Washington Post. Following so far?
The Saudi government hacked Jeff Bezos’ phone to blackmail him into killing Khashoggi’s stories (Bezos refused). So instead the Saudis hacked Jamal Khashoggi. Into little pieces. That killed him and his stories.
But then word got out that the Saudis murdered Khashoggi and everyone pointed to the head of the government, Crown Prince Mohammed bin Salman. He said he wasn’t involved, but it was just revealed that his personal What’s App account was indeed involved.
Most US politicians dismissed bin Salman’s denials outright. One major exception was Donald Trump. Trump just refused to push him on it. People figured Trump was trying not to piss off the Saudis, a major source of oil for the US and a major source of financing for Trump, Inc.
But maybe there was something else involved. Maybe the Saudis were providing Trump with information from Bezos’ phone. If they were, it will probably come out sooner rather than later and you can be sure the Washington Post will print the story.
