Biden is the quintessential Deep State puppet, and Assange and Snowden are at the tip of the spear trying to expose the Deep State. No way Biden would ever do that. Trump might have, but Biden, never. The Easter Bunny, or whoever is actually in charge, would not want that.
PDJT had the chance to pardon Snowden and/or Assange. However as per Bannon, PDJT was almost “threatened’ by bigger forces that he couldn’t deal with. Pentagon wanted Snowden eliminated as an example.
