Grusch has made the allegations that specific people and defense contractors are involved in illegal operations and are illegally withholding information from congress. So if you don’t think he will be tried for perjury as that article might claim, he can certainly be sued for false accusations. These are heavy allegations that go beyond just the standard lie
Probably somewhere along the specifying people and corporations that are conducting illegal activities - such as withholding information from congress and even killing people to protect this information. Even if congress doesn’t refer him to the justice department for perjury, the billion dollar defense contractors he’s making these allegations about should have no trouble suing him for defamation and false accusations.
They will go after him assuming he is not a part of an apparently nearly century-long, multi-state, multi-billion dollar conspiracy that they have been perpetrating in near secret. What I'm suggesting is that if you maintain a conspiracy that vast and for that long, why would an individual lying to congress be a bridge too far? Is public testimony about second-hand knowledge all that's been stopping this from coming out in the past?
Well, he’s alleged that whoever is apart of the conspiracy has killed to protect this secret. Perhaps people have been too afraid to whistleblower because their lives were at stake
