So they put confirm in quotes because it isn't actually confirmed. It is rather suspicious, but as stated >Zelikow, the executive director of the 9/11 Commission, told Insider he's skeptical that Bayoumi knew about the plot, or that he was working for Saudi intelligence. Many high-ranking Saudis, Zelikow pointed out, were despised by bin Laden and opposed to his efforts. "The information that Bayoumi might have been a paid informant ... if it is true, actually tends to cut the other way," Zelikow said — suggesting that Bayoumi would have been working against the hijackers. >Zelikow, for his part, remains skeptical. He suggested that the drawing and calculations might be related to Bayoumi's work with the Saudi Civil Aviation Authority. "It is possible that someone working in civil aviation might have worked on such equations, for various reasons," he said. So still unconfirmed, more of a clickbait title than incontrovertible proof
