I would think the State Department would be interested in what the crown prince of Bahrain has to say, regardless of some cheapskate donation (given the fabulous wealth of the sheiks) to a charitable foundation that pays the Clintons nothing.  James Comey seems to regard himself as the Chief Enforcer of classified documents regulation, and someone has to do it.  But he went beyond the bounds of his responsibility in dressing down the Secretary of State after he had found no probable cause to prosecute.  It is naïve to think his overstepping wasn't politically motivated - Comey was a Republican appointee left over in a Democratic administration.

As Ms. Parker says, the emails may reveal "who knows what."  Exactly.  I don't know, nor does she know.  At this point they seem to have revealed nothing of consequence.  Anyone inclined to suspect Hillary Clinton of criminal misdeeds has already made up her/his mind.
