What's up with Congress sticking its nose into potentially criminal acts? What legislation does this impact? Hypothetical question, I know the answer. Congressional hearing are conducted for the benefit of individual congressweasels. It's for show.
This will obviously “show” a lot about the criminality. Expect great results from this unveiling of this fascism.
IMO, there is quite a large role for Congress here: Not so much in seeking justice -- that's up to Sessions and his people.
However, while some areas seem fairly clear, there are multiple questions about the legalities of various aspects of all this. Some of these areas are discussed on other FR threads. It appears to me that Congress needs to write some very clear legislation with real teeth in it, to better protect our liberties.
Where is the attorney General on all this? Screw Kabuki CONgress, how about a Grand Jury..
You can bet some grandstanding Member will do something or say something that shields her from future prosecution.
Maybe it will even be done on purpose.
