Only problem with "obstruction" is it requires specific intent.
(That's different from violations of national security, like the ones Hillary did as a matter of routine. But you won't find that bit of info in The New Obstruction Narrative, will you?)
Sunstein, who is a committed Lefty lawyer:
...The much trickier issue involves obstruction of justice. On that count, the special counsel declined to reach a legal conclusion. In a sentence that will be much quoted, he said that “while this report does not conclude that the president committed a crime, it also does not exonerate him.”...
Of course, Sunstein knows that Bill Barr will brown-nose to Trump's advantage, based (I guess) on the pattern formed by Eric Holder and Loretta Lynch, who did a VERY good job of covering Barky and Hildebeeste.
Of course, it's possible that Trump did not "obstruct" at all--but that won't be considered by The Intellectualoid Establishment. Never.
