Yes. They should be held in contempt and fined. Barr should be impeached and Ross should be removed from office. Barr, in particular, needs to be made an example of. He is not and should never be the Presidents personal attorney in these matters. I hope there is a way to find his actions to be outright criminal. He should never be able to just block a legal congressional inquiry. He is violating the Constitution in so doing and he definitely needs to be made an example of.
