At one time Trump was considering the possibility of pardoning Assange but it looks like he never did.
"Did Mitch McConnell stop Trump from pardoning Assange? Senate leader told POTUS he would impeach him, say reports"
Regardless of the actual reason it's a shame Trump didn't pardon these people. It's also a shame that Mitch McConnell went along with the rest of the democrats (that Wikileaks embarrassed when they leaked information about the DNC primaries being biased against Bernie Sanders in 2016 ... see https://www.theguardian.com/us-news/2016/jul/23/dnc-emails-wikileaks-hillary-bernie-sanders [theguardian.com] ) opposing such a pardon. These people should be pardoned, embarrassing the U.S. government is not a good reason to go after them and that's primarily the reason they went after them. Shame on Trump and the rest of the government responsible for this insanity.
