Ex-FBI boss on big question left for Durham: Why did bureau pay Russian as source to spy on Trump?

Kevin Brock, former FBI Assistant Intelligence Director, discusses the bombshell dropped last night by Special Prosecutor John Durham says Igor Danchenko, the primary source for the discredited Steele dossier, was paid by FBI as confidential human source for three years despite prior concerns he was tied to Russian intelligence services. Brock says that the revelation last night, seems to point to that the FBI had "outcome bias, where investigators get so enamored with an investigative theory and belief that they stop hearing what their sources are telling or they only hear that which they want to hear.” But also that the Bureau seemed to have "a sense of urgency to run with it and believe what they wanted to believe.” Commenting that still, "we're left with a big question, why in the world did they feel like they had to sign up, Igor Danchenko as confidential human source of the FBI and then pay him?"
