So not only are you unable to tell me in your own words how Trump firing Comey obstructed the Mueller investigation, you are unable to give any of the "better examples" of your choosing and explain in your own words how that instance obstructed the Mueller investigation.
Pretty funny. 
I'm reading through it as we speak. I am aware of the Getbig Tit for tat mentality so I get your post. The thing is, I could spend days explaining to you the unethical behaviors of Donald Trump to which I have no doubt you would explain away or discard. So I am imploring you and others to READ THE DAMN REPORT. You can ignore this and remain safe in your cocoon or you could actually READ THE DAMN REPORT
Seriously, all kidding aside. I know it is fashionable to fight back and forth, but if you really are interested in what went on the report is full of info. If not.. then its politics as usual. Remember the Meuller report is fashioned from FBI interviews of almost everyone involved. The most damning information comes from people who are pro trump and were in his close circle of friends. The statements are in quotes and dated. I will say, had Trump not had some folks in his administration who flat out refused or ignored his directives, it would be even worse than it was.
