I think the guy might actually be telling the truth.
Allegedly he used very recently passed whistleblower provision in the NDAA to report everything about these black op programs to the intelligence community inspector general and that guy called David Grucsh and all the classified documents he was given "credible and urgent" in his report to Congress.
Also the Pentagon blocked all the representatives in the hearing that happened yesterday from debriefing Grusch's evidence of classified documents, names and locations of specific objects and people before the hearing in a SCIF, sensitive compartmented information facility, its literally a secured room with a Faraday cage and soundproofing to discuss classified things that can't be said in a public hearing to representatives.
