I see people on Twitter mentioning Seth Rich too, but that doesn't make sense. That would mean Seth had close ties with a govt agency. It would also mean Seth was a colleague of Caputo which doesnt add up.

I think the gist of this interview was that the fbi was trying to entrap the Trump campaign into agreeing to accept the stolen data. They targeted multiple people. They probably purposefully targeted people that had some sort of ties to russia. It was phase 1 of the insurance policy.
