I would be shocked if Obama & Co. weren’t aware, if not complicit, in Hillary crimes and treason. Perhaps the emails prove it. Maybe White House gave Comey the go ahead on Hillary in exchange for leaving them out of it.
Obama is trying to keep his hands clean because he knows they’re dirty. Doesn’t want to draw attention. He’s already been caught lieing about it once.
I think Obama just did that (if he hadn’t already) by this stance.
