Arrested is not the same as convicted. I consider this just more political theatre.
You may not be aware of this, but there has been a long term dissatisfaction at the State Department. This goes back a number of Secretaries of State and several Administrations. The Foreign Service Officers feel as though they are ignored, overlooked and generally insulted by the political appointeee, who tend to rely on their own circle of advisors. So it is not unusual to see them quit when there is controversy. I don't know Pompaeo, he may be a great guy, but I don't see him as a great Secretary of State. He doesn't have any kind of diplomatic background. No doubt at the moment he is taking his orders from Trump's lawyers.
I have to say, this is the most widespread time of politics playing out from within the professional workforce. I guess it is the TDS.
