You are correct; however, there has to already BE a crime in order to have some try to obstruct it, doncha think? Since he was found to NOT have committed the crime of conspiracy (there IS no such crime as 'collusion' which is why it isn't even mentioned in part 1 of the report) with Russia, there was nothing he obstructed. On the contrary, he, other than verbally and publicly showed his irritation, frustration, and anger over being accused of a crime he didn't commit, cooperated completely with the investigation.....not using Executive Privilege even once, sending over 1.5M documents and emails and texts, encouraging everyone in his administration including WH attorneys to cooperate and testify, telling even Cohen to tell the truth (even though he actually lied to Congress about everything EXCEPT saying Trump told him not to lie and that he had never been to Prague), and never fired anyone other than Comey (who the Dems wanted fired after July, 2017 statements about HILL) although he was constantly under fire by the media and Dems in Congress that he would fire Mueller and Rosenstein. Richard Nixon, Bill Clinton, GWBush, and BO ALL fought special/independent counsels and Congressional investigations every step of the way during their terms.....so show me where Trump was anything other than more transparent than anybody else?
You say there is a 'slim possibility he will be held to account'...…..for WHAT? For beating the bulls... back at them?
You DO realize that Barr wasn't, under law, required to put ANY part of that Mueller report out there, don't you? He was ONLY required to give his summary. He has offered to the leading Dems and Republicans and the Gang of 8 the chance to go to a skiff and read the unredacted portions that they are ALLOWED to see that are confidential and they turned it down. Instead, they are trying to use a subpoena to see it ALL, including the documents, and made available to ALL of Congress to see, and a court will deny them that ability because of laws on the books that don't give them that authority. This is all just wasted press time for their base, as usual, because they'll go out there and complain that Trump is blocking it because there is 'something he's hiding' or that the judge who makes the decision is one that Trump must have appointed. It's just more crap coming from them for the next two years again....but they only have 18 months or so to figure out that going own this road is at their own political peril because they will lose the House again.
