Kim Dotcom claims Seth Rich contacted him in 2014.

So, it seems that Seth Rich was on to the DNC corruption early on. Looking at Trump's apparent name tag mistake on June 24, 2018 on Twatter; POTUS guides people to @ClayHiggins18 for the next 1 hr and 7min. POTUS finally corrects name tag for Rep. Clay Higgins, but leaves the typo "are Vets" instead of correcting it to "our".
Meanwhile, searching through @ClayHiggin18's images (all of which prior to POTUS tweet) are all pretty outdated…very little activity. One image stands out and it says:
Haha I found our computers
The image posted on June 12, 2014…the same day that Seth Rich becomes National Data Director at the DNC.
I would also like to point out, and I do not know if there is any relation (and it is actually very hard to find any information on the person); but Seth Rich's boss at the DNC was a person named Sam McCabe (related to Andrew McCabe?) Info from DNC emails can be found on Wikileaks and you can see that the DNC gives him talking points when discussing the email leaks with the media.
