Washington (CNN) Jeff Bezos' stunning accusation that the National Enquirer tried to blackmail him mentioned the close ties between the paper's publisher, David Pecker, and President Donald Trump -- and a second, less well-known connection.

Bezos flagged the link between the New York tabloid's parent company, American Media, and the Kingdom of Saudi Arabia, returning to it several times.

While Saudi Minister of State for Foreign Affairs Adel al-Jubeir denied any connection between his country and AMI to CNN, Bezos said in his Thursday statement that the link between the Kingdom and the media company is not yet fully understood. He carefully laid out a web of connections.
