Even still, you’ve completely ignored the other half of my comment. Grusch is alleging specific people and corporations are involved in illegal activities. The corporations should have no trouble suing Grusch for false accusations and defamation, which in this case would be equivalent to jail time. So even if congress didn’t refer him to the justice department for perjury, those corporations absolutely will sue Grusch if he’s lying.

It's also a very different thing to lie to Congress with the backing of the IC (as happened with Clapper, WMDs, etc.) compared to lying to Congress against the IC's wishes. You are astronomically more likely to be prosecuted for the latter.

Do you have any evidence of this? The IC can refer you to the justice department on his own if you've lied to him/her.
