> “ In 2002, Bustani was negotiating with Iraq [to] join the OPCW, thus allowing its inspectors full access to Iraq’s purported “chemical weapons arsenal”. If Bustani had succeeded, this would have impeded the Bush administration’s war plans, by removing one of their “weapons of mass destruction” pretexts. When John Bolton got wind of Bustani’s efforts, he demanded his resignation. In a phone conversation between the two men reported in The Intercept, Bolton is quoted:

It wasn't a phone conversation. Bolton went to The Hague in person, 
according to the report in The Intercept.

I very much doubt that Bustani is still with the OPCW. In his statement on 
the whistleblower's revelations, he says:

"The convincing evidence of irregular behaviour in the OPCW investigation of 
the alleged Douma chemical attack confirms doubts and suspicions I already 
had. I could make no sense of what I was reading in the international press. 
Even official reports of investigations seemed incoherent at best. The 
picture is certainly clearer now, although very disturbing."

He read about the Douma incident in the international press and in the 
official OPCW reports (interim report and final report).
