Well-know pundit (and Lawyer) Lionel addresses the question of whether Mr Mueller is in fact operating within the bounds of the law after an article appeared in the WSJ on this issue.
The inescapable conclusion is that Mueller is acting far beyond the scope of his authority and is in all likelihood acting Illegally and Unconstitutionally.
On this basis there is little chance ANY of the supposed indictments made by Mueller can be upheld in court. However the impact in the Court of Public Opinion would be devastating - which is likely why President Trump dares not to order a shut down of the investigation.
But as the investigations by the Senate Intelligence Committee proceed apace it seems that more and more an advantage is accruing to the President as the Deep State machinations are being bared for all to see - and it ain't pretty.
