The elephant in the room is the degree of direct involvement President Obama had in the politization of the FBI and DOJ. It seems unlikely Comey, Lynch, Strzok and McCabe acted without Obama’s knowledge and approval.
As far as I am aware, documents showing POTUS involvement have not turned up. Can it be no one kept records or notes? I find it hard to credit this group of plotters with that much criminal cunning.
The ultimate questions: What did Obama know? When did he know it? Why did he permit (or foster) it?
