"Br'er Rabbit  (Donald Trump) keeps slapping this "Tar Baby" (Russian Scandal)  and is only getting more stuck to it.  This is now becoming an uncontrollable news event for an Executive who depends on controlling the news cycle.   Unlike other Presidents, Donald J. Trump has several "Br'er Foxes" (opponents from both major parties) who must be  gleefully watching this self-entrapment and will be working to ensure there will not be that "Brier Patch" where the rabbit can escape.
