Plausible Deniability : vimarsana.com

That’s a phrase used by James Biden (Joe Biden’s brother) in describing the shady activities of the Biden family in international business dealings.  A definition of that phrase goes as follows:  “The term typically implies forethought, such as intentionally setting up conditions for the plausible avoidance of responsibility for one’s future actions or knowledge”.
That sort of sums up the actions of the members of the Biden family in their “shady” dealings with foreign countries using the name “Biden” as the “foot in the door”, to get monetary rewards which they would not be able to get if they didn’t use the Biden name or his influence.
