Ben Stein is the Nephew of an accomplished academic economist, whose name was also Ben Stein, if my memory is correct. Ben Stein, the actor, was an economist and, again if my memory is correct, he worked in the Nixon Administration, As I pointed out above, the investigation was never charged with finding collusion. And they made no allegations of Bestiality, which they also did not look for. They did find dozens of people breaking a number of campaign laws and other statutes.
They also found that the Russians, independent of the Republican Party or President Trump, laid the groundwork for influencing the election outcome in 2014. The International Research Agency of St Petersburg, Russia set up hundreds of Facebook and other social media accounts and built followings for political content they posted. They also hacked the private E-mails and other on-line content of Hilary Clinton and almost 60-high ranking Democrats. They made this information available to Republicans through Wikileaks and directly through third parties not associated with the Russian government.
The most politically charged, and probably most interesting, exertion of influence was the planting of Paul Manafort directly into the hierarchy of the Trump Campaign. Manafort came to the campaign as an unpaid volunteer and was given a job at the top of the leadership group. His last paid job was working for suspected Russian Spy Konstantin Kilimnik on the campaign for the Pro-Putin President of Ukraine. Kilimnik was indicted by Mueller, but he had fled to Russia where he was protected from extradition. Manafort, who allegedly liked to "live high on the hog," was convicted of financial crimes unrelated to his association with the 2016 Trump Campaign. He has somewhat quietly assumed a role with the 2024 Trump Campaign.
