Would Biden be taking on and continuing trumpy era legal grudge cases like Assange;
or maybe quietly letting them slip off the priority 'to do' list...???

The Assange business started during the Obama administration. This will hold more context for Biden than some of the other things Trump has mangled over the last four years.

As a journalist I have mixed feelings about Assange. Publishing the Manning stuff was one thing; publishing the Clinton emails as a tool of the Russians and Trump were entirely another and put his journalistic motivation to question.
