The co-founders of Fusion GPS, Glenn Simpson and Peter Fritsch, speak out to "The Investigation," breaking their silence about the origins of the now infamous Steele Dossier and weighing in on the current impeachment inquiry involving Ukraine. "We were horrified when it [the Steele Dossier] was published because it's not the kind of thing that we do," Simpson told "The Investigation," of the publication of the raw information, adding that the information that Steele, a former MI6 agent hired by Fusion, brought back to them was "a digital Pearl Harbor...the government of Russia attacked our political system." The two former investigative reporters who were original hired by the Republicans to investigate then candidate Donald Trump leading up to the 2016 election have released a new book entitled "Crime and Progress: Inside the Steele Dossier and the Fusion GPS Investigation of Donald Trump."
