Trump loves Putin. Trump loves Putin’s Russia and the way he commands things there and gets rich by it.

Trump loves Putin. Trump loves Putin’s Russia and the way he commands things there.
It may not be such a great idea to defer talking to Flynn. Or, at least put him up in a safe house.

Also, be wary of Putin taking advantage of this situation and inflicting still more turmoil upon the U.S. by arranging to have Flynn killed, framing Trump.
As one long-time analyst of Putin said a while ago now, “Putin is going to eat Trump like a sandwich.”
