" than to simply cop to the fact that they are aggressively and overly supporting Donald Trump."

This is hard to swallow.

There is nothing in Wiki/Assange past behaviour that would indicate they would like to support Trump.

Unless: They like 'whoever is against Hillary'

OR

Wiki is getting a lot of support from Russia, and they may be indirectly leaning towards conspiring with them for political favour etc..

Putin just might have enough pull to eventually get Assange out of his prison.
