No, seriously mate... and I know you like your short non-engaging quips, but is there a serious explanation out there? If as the President has now alluded to he thinks Comey is lying why get involved in a cheap theatrical. The Senate hearing(s) are a stage provided for public grandstand purposes and for whatever reason they seem to want to give a stage to Comey. Fine let him say his piece, he's got a story tell and the ramifications of that Story will probably run to nothing in the long run as these things always seem to do.
However, the White House retains its own counsel whose role is to advise the President in his capacity as President on (certain) issues arising to and of the President whilst in office, in the case of this caffuffle or dispute with Comey it has occurred during Trump's term as President - so why has Trump engaged external counsel? Is he affraid of the attorney-client privilige that exists between the office of President and the office of the White House counsel if so then Why? If there are issues with that state of privilige then I would understand his retaining personal counsel as then that disclosure of information and attorney client privilige is not open to public question or scrutiny. Which goes back to my original though as to why is Trump (he) personally (not as President) engaging in a private shit fight with Comey and unleashing attack ads on Comey through non-White House organs?
Is the collection and subpoena of information and persons being undertaken by White House counsel or private counsel?
Why is he not staying alloof from this and allowing White House counsel to take the lead?
Am I missing something?
