Look, if Mueller, with his staff of Democrat investigators could not come up with anything, you need to accept that.
Mueller detailed the collusion that we all saw happen in plain sight, as well as numerous examples of obstruction of justice that also happened in plain sight.
The DOJ guideline requires that Congress take up what can't be prosecuted.
That now over 800 legal experts have weighed in to the effect that anyone else would be prosecuted for obstruction of justice is what YOU need to accept.
Your attempt to compare Mueller with the people you listed is idiotic, even for you.
