As stated time and time and time again. Mueller was never going to indict the president, he was prohibited per DOJ policy of doing just that.
What he could have done is list out possible indictments, explicitly, that Congress could use for Impeachment.
He didn't even do that.
He listed specific instances where the president attempted to obstruct justice in the report
indictments was a waste of time as per DOJ regulations that as a sitting president Mueller lacks the ability to indict Trump
Thus it is quite obvious that the report was meant for Congress who has the only means of holding a sitting president accountable
It would be a circus if the President had to go through a regular trial in the judicial system especially with appeals and delays and whatnot. How would you get jurists. Ask them if they are repubs or demos. Sounds like a hung jury.
Also Mueller could not even get trump to give statements in the normal way. I mean submit questions to the defendant and wait for the response. The response by Trump in most questions was "no recollection"
just as Clinton was never indicted for lying in the judicial system , but instead the senate did the trial as the house who has the sole power to impeach recommended impeachment but the Senate (the court) found him not guilty
Mueller had no way to indict him per DOJ regulations, he could only hand over the material that can be used in the impeachment process
As Trump would suggest this is not a do over, this is a continuation of the process
It may have ended if Mueller had exonerated him in the obstruction of justice matter
Congress still has it say
