A number of members of the US Congress have stated the opinion that the fact that President Trump twitted his opinion of Muller's investigation, before it concluded, amounted to an obstruction of justice. The purported basis for this was that he was a potential future subject of the investigation.
Attorney General Barr stated, during a previous Congressional testimony, that he intended to pursue an investigation of the genesis of the collusion allegation against the President.
After yesterday's Congressional testimony, a number of Congressmen twitted that Barr should resign. As potential subjects of Barr's investigation into the origins of the genesis of the collusion allegation, did these Congressmen not commit obstruction of justice with their twits?
It seems to me that either both Trump and anyone demanding that Barr resign committed obstruction or none of them did.
Am I missing something? Or this outside of the purview of the law and the discussion is completely political?
