"According to the Mueller Report, WikiLeaks had received an email containing an encrypted file named "wk dnc link I .txt.gpg" from the Guccifer 2.0 GRU persona on July 14, which was four days after Seth Rich died.[80][81][82] In April 2018, Twitter direct messages revealed that even as Assange was suggesting publicly that WikiLeaks had obtained emails from Seth Rich, Assange was trying to obtain more emails from Guccifer 2.0, who was at the time already suspected of being linked to Russian intelligence.[83] BuzzFeed described the messages as "the starkest proof yet that Assange knew a likely Russian government hacker had the Democrat leaks he wanted. And they reveal the deliberate bad faith with which Assange fed the groundless claims that Rich was his source, even as he knew the documents' origin."[83]"
So, there's no evidence, other than people with at best a vested interest against the Clintons or obviously compromised by Russian intelligence - if you work with them once, they've got you.
