In November 2017, Saudi Crown Prince Mohammed bin Salman (MBS) ordered the arrest and detention at the Riyadh Ritz Carlton Hotel of over 200 members of the Saudi royal family, including eleven rival princes, as well as government ministers and influential businessmen. That came after an October 2017 meeting in Riyadh between MBS and Donald Trump's son-in-law, Jared Kushner, conclave that lasted well into the early morning hours. At the meeting, Kushner is said to have turned over to MBS a list of the names of the Crown Prince's opponents: leading figures of the Saudi royal house, government, and major businesses.
The list may have also contained the name "Jamal Ahmad Khashoggi."
The list of Saudi names was, reportedly, compiled by Kushner from top secret special code word documents he had specifically requested from the National Security Agency (NSA) and Central Intelligence Agency. The documents were specifically requested by Kushner, not because he was an expert in communications intercepts, but because he likely had a control officer who told him what files to obtain. The Kushner family have longstanding ties to the Israeli Likud Party, as well as the Mossad intelligence service. The Mossad enjoys a close working relationship with the Saudi General Intelligence Directorate, which is now firmly committed to MBS after a previous purge of its upper ranks following MBS's rise to the heir apparent position in the House of Saud.
