JA doesn't have the thumb drive.  There was another guy (a police detective, can't recall his name at the moment) who picked up the thumb drive from Seth Rich.  The police detective drove all the way up to D.C. from So. Florida, picked up the thumb drive and drove back down to FL in one 24 hour period.  Seth Rich had posted to this detective's blog (about corruption in Ft Lauderdale Justice Depts) that he had "something"....something in the bombshell category.  That's why the detective drove all night long to get it.  Once he got to D.C. Seth Rich told him what it was....DNC emails. The data was then uploaded to KimDotCom's website, and from there, Julian Assange accessed it, and published it on WikiLeaks.  The Fl Detective was in contact with Julian Assange to tell him where to access the Seth Rich DNC email data. Thats the trail or chain of custody of the evidence.  Seth Rich >>> Fl Policeman/Detective >>> KimDotCom's website >>> to JA WikiLeaks.  All participants in this chain of evidence are KEY Witnesses. This is why Kimdotcom was extradited to the USA on phony charges too, to get his testimony.  Now the same thing appears to be happening with Julian Assange. Since this evidence is critical to prove that Hildabeast knew there was no Russian Collusion, it is part of the case for her Military Tribunal for TREASON.  Trump is not going to be sloppy about caring for the safety of these key witnesses. I believe the FL Detective high tailed it out of the USA after he did his part (considering what happened to Seth Rich), and if I recall correctly is making pc furniture in Russia, where he is hiding out.  He has a website for his furniture.  Anyway, this detective has the thumb drive, if he hasn't already turned it over  long ago to Attorney General Jeff Sessions.
