Anon yesterday had it on the money I think.
Mueller going for manafort's finances.
CNN perspective: "why finances and not Russia?"
Fox perspective: "why finances and not Russia?"
Manafort finances → shady loans → why paid? → By who? → why?
The Mueller white hat theory goes like that.
PM → AM → BHO.
I think this also is very comfy with Q's "How do you legally…"
