He also claims Khashoggi himself was “extremely controversial”, adding “a lot of people didn’t like that gentleman that you’re talking about, whether you like him or didn’t like him, things happened, but he [the prince] knew nothing about it”.
Bin Salman chips in to say he feels “painful” about the families of 9/11 and on the journalist also says it is “painful” to hear of anyone losing their life “for no real purpose”.
He also calls the killing a “huge mistake”.
He insists the “right steps” were taken during the investigation and says the system has been improved “to ensure nothing happens like that [again]”.
