Not totally following your logic... All of the above should have been forced to testify about any wrongdoing. Does that justify completely shutting down all the current and past Trump white house aides from testifying about anything? Are we just giving up on all accountability and oversight? I guess you are full bore for totalitarianism because that's where we are headed. At least two major players have mentioned concerns that if Trump loses in 2020 that he might not be amicable to giving up power. What then... civil war?
It's political games. Clinton's admin did it when he was getting drilled by Ken Starr. Remember that ridiculousness? Bush/Cheney 43 did it. Obama did it in regards to Fast and Furious.
Actually, I WANT Congress to stand up and do their job, on many fronts, but they are just bought and paid for.
Of course I am not for totallitarianism. I am for personal liberty.
No matter who was going to be POTUS, our country, the world, is slowly heading toward a totalitaran existence. Surveillance is becoming more prevalent. Biometric ID, FinCen, Patriot Act, NDAA, Facebook, Amazon, GOOGLE. "Technocracy". Check out the excellent book by Patrick Wood "Technocracy Rising". Or this online book:
Audiobook: How the Specter of Communism Is Ruling Our World
To your point about Trump losing and not giving up power. The right was all panicked that Bill Clinton would not leave power, would suspend elections. The right was panicked as well about Obama not leaving office.
As for civil war, we are closer than many think IMO. We are being divided, sub divided. We are being herded to various tribes.
