There really isn't much to explain. This is yet another manufactured story, like Vince Foster, emails, Bengazi, all of the Nunes stuff down to Uranium One and Page-Strozak where the right is trying to do something to distract from its own actual crimes against the United States.
This has nothing to do with the current story. However, everyone of those things--with the exception, perhaps, of Vince Foster--has some basis in reality. And, please think about this--if one of Trump's senior advisors committed suicide, don't you think there would be some suspicions?
Emails: Comey did everything but say Clinton was guilty. There are certainly many reasons to believe the investigation was not conducted properly. Including a very inappropriate meeting on the tarmac between Bill and Loretta.
Benghazi: sending Rice out to repeat a lie five times on Sunday shows--when Clinton herself told Chelsea it was terrorism.
Uranium One: this is definitely troubling. Once more, if this happened with Trump, the Dems would be screaming, and so would the media.
Page-Strozk is documented. They were demoted and there is no question that Strozk was a powerful investigator at FBI. If this does not trouble you, you are in the tank with him or incredibly naive.
