I wonder if this is a reminder to the Clintons, Hillary in particular that they are not welcome to participate in certain DNC functions.
Or consider running in 2020.
This is a CNN gambit to draw the curtain back a bit on the “independent prosecutor” function. I think CNN is assuming that Ken Starr had a lot of supporting evidence on the Clinton’s that will finally make the case that Bubba should have been removed from office. CNN’s gamble is that the public will draw the same over-generalized conclusion about the current Trump investigation — that Mueller has more cards than he is showing.
I think that this will backfire, and that it will be the final nail in the public lives of Bill & Hillary. The next we’ll see of them will be their funerals (although Hillary’s will be private).
