I believe Donna and Seth were working together to take down clinton. I believe they were both working with Bernie Sanders to prove hillary cheated. They were trying to take down hillary from inside the party. Donna and seth were trying to get clinton disqualified from running. So Bernie could run. She got caught ( I believe on purpose) giving hillary the debate questions. And Seth copied the original documents from the DNC which would prove they were altering the documents for hillary. I think awan was altering them to hide money traces. They found out and traced it to seth.
Meanwhile NSA was watching and allowing this to take place. Letting the democrats destroy themselves. I believe they stepped in after learning of the plan to kill him. Most likely bulletproof vest and then took him to a preset hospital where they took him into witness protection and claimed he died on the operating table. Donna brazile was at the hospital and witnessed high security with no one being let in or out of the operating wing. At this point i would suspect that she was offered a deal to help and avoid criminal prosecution. Same with Seth.
NSA most likely watched communications between deep state leading up to assassination of seth and watched the clean up crews being activated. Watching and recording the crimes. Watched them kill the ms13 hitmen and report back the the top.
I believe Seth and Donna are the Source. Q said we have the source.
Just a theory from everything official thats come out. None of what they said makes sense any other way.
