al_Qahtani has published odd tweets the last weeks and in this https://twitter.com/saudq1978/status/1053493341147578368 he thanks the king and MbS for all their time together and their trust in him. He as well says that he will be loyal for all eternity.
According to https://kozpost.com/blog/khashoggi-who-are-the-two-senior-saudi-officials-dismissed/12479/ he tweeted last year: “I do nothing of my own initiative, without orders. I am the employee and the executor of my king and my prince”. Unfortunately it was no link to that tweet.
