How is this a “highly sensitive case?” Just because “political royalty” is involved?
Of course, and rightly so.
It's not the "Clinton = royalty" part that makes it highly sensitive. It's the "Head of the Executive Branch disqualifying a potential replacement" that makes it sensitive, which is as it should be.
It's not that they're both Democrats - if Romney were the President and the FBI was investigating the Democrat running to replace him, it would be MORE sensitive.
