I found this article from three months ago.
This was the third time Comey investigated the Clintons, to no effect.
First, Special Deputy Counsel to the Senate Whitewater Committee.
Second, as U.S. Attorney for the Southern District of New York, He inherited the investigation into President Clinton’s pardons for contributions. No charges.
Third, was the current investigation into the email server.

Comey has caused severe damage to the FBI. Some wondered if he was being blackmailed but it seems it’s greed.
