Clarification on Mueller Investigation

Make sure I understand this correctly:
An investigation, a report, that could dramatically impact our federal government, up to and including the possible impeachment of a president and even his VP at the same time, in which hundreds of hours and millions of dollars have been spent to piece together what are likely some of the most egregious crimes in the history of our nation’s government, could simply disappear in a puff of smoke as if it never existed once completed and given to the attorney general’s office? Apparently there is absolutely nothing anybody can do about it?
So, really, what the fuck was the point? The AG can just stop all Justice Dept effort to do anything about any of this. An AG that was put in office by trump and who, on paper, is likely a criminal himself if some of his previous associations are true.

Lol..whatever. What did I expect? Guess trump can literally do whatever he wants and no one can do anything about it. No one really cares anyway. I hear more bitching and complaining and attacks on a freshman female member of Congress than trump so I guess I shouldn’t be surprised.
