That is what the AG is saying in this case.
In making this determination, we noted that the Special Counsel recognized that "the evidence does not establish that the President was involved in an underlying crime related to Russian election interference," and that, while not determinative, the absence of such evidence bears upon the President's intent with respect to obstruction. Generally speaking, to obtain and sustain an obstruction conviction, the government would need to prove beyond a reasonable doubt that a person, acting with corrupt intent, engaged in obstructive conduct with a sufficient nexus to a pending or contemplated proceeding. In cataloguing the President's actions, many of which took place in public view, the report identifies no actions that, in our judgment, constitute obstructive conduct, had a nexus to a pending or contemplated proceeding, and were done with corrupt intent, each of which, under the Department's principles of federal prosecution guiding charging decisions, would need to be proven beyond a reasonable doubt to establish an obstruction-of justice offense.
