The end of the Special Counsel's investigation into the non-existent conspiracy between President Donald Trump and the Russians has created an army of "Mueller Truthers," demanding additional investigations. But Republicans are also demanding to know more, specifically how the FBI came to look into collusion, and what that tells us about the tension between America's political and intelligence worlds. In Rudy Giuliani's words "Why did this ever start in the first place?"
The primordial ooze for all things Russia began in spring 2016 when the Clinton campaign and Democratic National Committee, through a company called Fusion GPS, hired former MI6 intelligence agent Christopher Steele to compile a report ("the dossier") on whatever ties to Russia he could find for Trump.
Steele's assignment was not to investigate impartially, but to gather dirt aggressively—opposition research, or oppo. He assembled second and third hand stories, then used anonymous sources and Internet chum to purported reveal Trump people roaming about Europe asking various Russians for help, promising sanctions relief, and trading influence for financial deals. Steele also claimed the existence of a "pee tape," kompromat Putin used to control Trump.
