Seems clear that at least back in 2017, Julian Assange had some concerns about Mike Pence.

I have concerns about Pence in 2021. Do you?

Julian Assange – “Clinton stated privately this month that she is quietly pushing for
a Pence takeover She stated that Pence is predictable hence defeatable.

Two IC officials close to Pence stated privately this month that
they are planning on a Pence takeover Did not state if Pence
agrees.” – 2017
