Even if Mueller could prove that members of the Trump team had colluded with Julian Assange to use material that Assange had unlawfully obtained, that, too, would not be a crime.
Merely using the product of an already committed theft of information is not a crime. If you don’t believe me, ask the New York Times, the Washington Post, the Guardian and other newspapers that used material illegally obtained by Assange with full knowledge that it was illegally obtained.
In the end, Mueller should be judged by how successful he has been in satisfying his central mission. Judged by that standard and based on what we now know, he seems to be an abysmal failure.
The recent guilty plea of Michael Cohen of lying represents the dominant trend in Mueller’s approach to prosecution. The vast majority of indictments and guilty pleas obtained against Americans by Mueller have not been for substantive crimes relating to his mandate: namely, to uncover crimes involving illegal contacts with Russia. They have involved indictments and guilty pleas either for lying, or for financial crimes by individuals unrelated to the Russia probe. If this remains true after the filing of the Mueller report, it would represent a significant failure on Mueller’s part.
Mueller was appointed Special Counsel not to provoke individuals into committing new crimes, but rather to uncover past crimes specifically involving alleged illegal coordination between the Trump campaign and Russian agents. No one doubted that Russia attempted to influence the 2020 election in favor of Donald Trump and against Hillary Clinton. But Mueller’s mandate was not to prosecute Russians or to point the finger at Vladimir Putin. His mandate was to uncover crimes committed by the Trump campaign with regard to Russia’s attempts to influence the election.
