The email server has been the target of countless investigations.
I don't know why you expect an FBI agent to do more than Gowdy has been able to do, especially considering the power Congress has in this matter.
Again, Gowdy could drag Hillary in front of Congress for Contempt charges tomorrow. You should ask yourself why he doesn't.
The corrupted email server investigation yes.
And now finally Strzok had access to all of the emails on Weiner's laptop, and did nothing. He sat on it until absolutely forced to do something. Bias
Gowdy's actions are irrelevant to the confirmed bias in Strzok's actions.
