From Kim Strassel, here:
[T]he process highlights not only the absurdity of Mrs. Clinton’s claim that her server was no big deal, but also the irresponsibility of the FBI’s decision not to prosecute. Duly elected members of Congress are traversing layers of security and guards, clearances in hand, to view a few top-secret documents. Ask Mr. Comey why what is demanded of them was not demanded of Hillary.
But the contradiction gets even more extreme. The FBI has placed additional, and unnecessary, strictures on the Hillary file. It warned lawmakers against publicly sharing any information from the documents—even unclassified information. So the FBI chief won’t prosecute Mrs. Clinton for spreading secrets across the globe, but he bars Congress from talking about unclassified issues that potentially get to the heart of today’s presidential race. One might wonder why. ...
The entire spectacle—from the investigation to this week’s handover of files—demonstrates how much damage Mr. Comey has done to the FBI’s credibility.
