I am not aware of another president who has weighed in against ongoing criminal prosecutions in the overt, hostile, and unrelenting way that President Trump has. This is a breach of propriety and of historical norms. Presidents don’t weigh in on those things. They don’t try to tip the scales of justice for or against a particular defendant. In our system, intervention from the outside is not only considered inappropriate—it is inappropriate. It undermines the operation of a fair system of justice. It sows seeds of mistrust.
