In the next few years the investigation that will, in all probability, have led to the downfall (via impeachment and removal, resignation under imminent threat of same, or landslide defeat in the election of 2020) of America's worst president in living memory and (deus volent) his conviction and imprisonment for conspiracy, obstruction of justice, perjury, tax evasion, money laundering, and/or treason will certainly be the subject of one or more major theatrical and/or high-budget television productions. What actor do you think has the appearance and the gravitas to most convincingly play the principal architect of that investigation?
