Thanks for the pre-Trump & pre-Sessions start date. The link above addressed the Vermont R Party generating the complaint. How it got to the FBI is the work of DiGenova and Toensing. The story left that dot out. The law firm was messing with the Obama Justice Department, with this filing.
Interesting how incoherent these stories are, lacking chronology and decent basic journalistic competency.
Thanks for filling in the blanks.

Although reporters largely ignored the letter at the time, Politico reports that a federal investigation was indeed launched. "Federal investigators and FBI agents started to pull apart the $10 million financial arrangement. They showed up at Burlington College to sift through hard drives, audit reports and spreadsheets. They began to interview donors, board members" and a past president, reported Politico, which added that a second letter to investigators accused Bernie Sanders's office of applying pressure to help his wife get the loan for the school.
Looks to me, applying the DEM standards used vs. Trump, that Bernie is obstructing justice.
I recommend the article.
