Whatever the crime, however obvious the verdict.Under the Law as practised in the USA, a person is innocent until arraigned before a Court of Law, tried before a Jury and subsequently found to be Guilty.
Thus it should be patently obvious that as before any trial he is considered to be innocent, no Legal action can be taken to remove him from office by way of a court order.
Thus legally speaking he can only be removed from office by Impeachment or by voluntary resignation.
Having said that, of course in my opinion he is as guilty as hell.
But what do you (the great American public) imagine?
That you have honest Politicians?
