The first order of business for the special prosecutor would be to determine how badly compromised/sabotaged the FBI investigation was by White House/DOJ instructions and the FBI director’s interference.
If I was Mr. Weasel ... er, Comey, I would be worried.
Then conduct the investigation with a properly scoped mandate and investigators authorized to examine every aspect of Clinton’s time as secretary of state (to include tie-ins to the Clinton foundation).
Let the chips fall where they may. I don’t particularly want her or Bill in jail (don’t want to pay for their expenses) but I would like the Clinton brand made so infamous that they leave American politics forever.
I even have no problem with investigating the 22 million emails that they claim Bush destroyed to make it even less partisan in nature.
