In the early days of the Corbett Report, James Corbett often used to do presentations with an FBI whisleblower called Sibel Edmonds.
None of this is what it seems, & I think James Corbett came to realise she was a shill but this was the official story:
Sibel Edmonds is a former contract translator for the Federal Bureau of Investigation (FBI) and the founder and editor-in-chief of the independent news website NewsBud.
The FBI hired her as a translator shortly after 9/11 but fired her after less than seven months. She identified herself as a whistleblower and challenged her termination; however, the courts dismissed her lawsuit for wrongful termination because the FBI would need to disclose privileged information. She accused a colleague of covering up illicit activity involving Turkish nationals, alleged serious security breaches and cover-ups and that intelligence had been deliberately suppressed, endangering national security. Following her accusations, the US attorney-general imposed a state secrets privilege order on her, which prevents her from revealing more information about the FBI.[4] The PEN American Center awarded her the PEN/Newman's Own First Amendment Award in 2006 for her claims.[5] She published a memoir in March 2012, titled Classified Woman – The Sibel Edmonds Story.
