Somewhere in all this it seems to me that the acts of alleged obstruction did occur. Barr admitted to such when he said Trump was frustrated & angry that the Russia thing would undermine his presidency so he acted to obstruct it. Simple. And it's just plain wrong in a serious way. The American people need to understand the character, breadth & depth of Russian efforts so as not to fall for them again. We also need to lock up high flying miscreants like Manafort, Gates, Flynn & maybe Roger Stone as well. None of that would be as it is if Trump had his way.What the Senate will or will not do doesn't alleviate the House's responsibility to carry out its task. If the President meets the requirements for impeachment as many in the House has stated as a fact they should impeach. It is their duty regardless of the Senate. Then it is the Senate's responsibility to convict or not.
As Hyman G. Rickover said:
“Responsibility is a unique concept... You may share it with others, but your portion is not diminished. You may delegate it, but it is still with you... If responsibility is rightfully yours, no evasion, or ignorance or passing the blame can shift the burden to someone else. Unless you can point your finger at the man who is responsible when something goes wrong, then you have never had anyone really responsible.”
