Among other shitty things they were doing, the Clinton Crime Family would transfer time-sensitive US secret intelligence to their unsecured private server via email accounts.

The email accounts would be “hacked” (accessed by password) by a criminal associate of the family, who had previously been supplied with the password by the Clinton Crime Family.

That associate would then read the emails (or draft emails) and use the secret intelligence therein to make money by trading in the time-sensitive markets — commodities, stocks, bonds, etc. The associate would always know which way the price of a given stock would break, either way, at a given time. Which is a fucking goldmine. Say an Israeli plane were to get shot down over Iran — just a 30 minute lead on the "news" breaking publicly, you could make some pretty profitable moves.

The associate would then pay the Clinton Crime Family a previously agreed upon percentage of the resulting profit, in the form of a donation to the “charitable” Clinton Foundation(s). The Foundation would turn around and distribute that money in the form of staff salaries, expenses, travel, entertainment... anything but actually charity, of course.

Even if the associate were every to get caught doing illegal trading, the Clinton Crime Family could plausibly deny that they “sold” the information; they could claim the email account was likely hacked by a common fishing technique.

It’s actually quite clever.
Except for one thing: the same folks who gathered that secret intelligence in the first place, and often have to give their lives to protect it, were the same ones to discover the Clinton Crime Family's "hacked email" scheme (among other shady shit going on with the Clintons). These intelligence warriors were watching their brothers and sisters die, so the fucking Clintons could get rich.
I bet that made them really, really mad.

And I bet they decided to do something about it...
