You are a living example of the ignorance I am tal... (
Barr interpreted the Muller report, Muller answered back once then bowed out.
It was 8 months ago Barr got the report, and when was the last time Muller said anything about it ?, 4 months ago that when.
The GOP is backing Trump while his economic policies are working for the US economy which means working against almost every other Nation on earth, so it will be touch and go if Trump can survive for 2020, with the Neoconservative agenda failing in Latin America and the Germany.
Trump's manner is being questioned as technically prosecutable obstruction, however Trump's only obstructing the well being of Americans if his policies are causing uncertainty, conservatives are supposed to be the opposite, I think his policies are causing uncertainty but necessarily so in many ways.
Trump's policies are legitimate but his way of communicating with people is
so unorthodox the Globalists feel they can bring him down with complex arguments, if Trump was deliberately trying to enlist Zelensky into waylaing Joe Biden he would have used a back door method that is both obvious and overlooked, and Muller couldn't have injected the obstruction issue and then retired, if he'd did the issue would have gone away, Barr brough obstruction to the centre of attention.
So either Trump is not knowingly infringing accepted standards of protocol or he's settling out to shaft himself, because knowledge is 99% of credibility as you said in your opening post, but knowledge can not be the prerequisite for in depth legal procedures and it's not.
Barr I think doubled down on Muller and opened the gate to the impeachment inquiry by raising obstruction issues, so I agree with you about that technical issue but it's not very important, Trump doesn't need to make concessions to his financiers until his second term ends, if he does make concessions before 2020 he won't have a second term, "Concessions means Demands", and the period of Neoconservative austerity that Trump represents appears to be ending, or even over completely, the IMF, World Bank and Bank of International Settlements now want to change course.
I believe Dominique Strauss Khan was "mind controlled" by these people the last time IMF (ect.) wanted to change course 2011, they wanted to break from the UN at that time, but now feel Trump's adventurous policies have failed and want to roll them back with the appeasement policy that Dominique Strauss Khan stood for, Trump can't really understand what's going on.
