Report's vol two lacked evidence of obstruction. Pointed at new stories – mostly those that made assertions and innuendo of wrongdoing via anonymous sources. That is all his team produced. Shallow allegations. Unsubstantiated.
So regardless of constitutionality of an indictment (sealed or otherwise), there was nothing in the burger.
But his additional point about sealed indictment being unconstitutional is a bit strained, really. The constitutional restriction, as inferred by DOJ policy analysts and policy-makers of previous Admins, is inapplicable to someone who is no longer a sitting president.
Can lawfags clear this up? If the indictment is sealed, on ice until the individual is no longer in office, would that not be constitutional?
