It explains that under long-standing department policy a president cannot be charged with a federal crime while he is in office. That is unconstitutional. Even if the charge is kept under seal and hidden from public view, that too is prohibited. The special counsel’s office is part of the Department of Justice and by regulation it was bound by that department policy. Charging the president with a crime was, therefore, not an option we could consider.

It would be unfair to potentially accuse somebody of a crime when there can be no court resolution of the actual charge. So that was Justice Department policy. Those were the principles under which we operated and from them we concluded that we would not reach a determination one way or the other about whether the president committed a crime.

Mueller acted appropriately by not giving into the bait by democrats to make a judgement call. For the president, the Mueller investigation isn't a trial, the purpose isn't to assert guilt, it was to gather evidence that Congress is responsible for reviewing because it is the sole entity with the ability to levy charges against the president.

That is why Barr is being held in contempt for refusing subpoenas from the single entity in the world that is able to make a judgement on this case. Paul Manfort, Michael Flynn, Michael Cohen, George Papadopoulos, Alex van der Zwaan, and Richard Pinedo have all been tried, found guilty, and sentenced after making testimony that the president instructed them to engage in the crimes for which they have been convicted. That is why every prosecutor on the hill is confident that Donald Trump will be an easy conviction when it eventually makes it to trial, but that only happens when he is either no longer president, or the house decides to push forward with impeachment.
