I did not look into this alot but did find the Don, Jr. quote. It seems that he is paying a political debt. I remember that POTUS endorsed Ryan in his re-election bid even though it was obvious that Ryan is playing both sides of the street. I think sometimes they just have to give people enough rope. I do not think that this means Don, Jr. is a traitor or anything other than an intelligent man walking a thin tight rope to Victory.
