mueller was carrying out his original mandate. his original mandate was primarily to take over a counter intelligence investigation that was about what the russians did. that's what comey was doing at the fbi. when he got fired. that's what mueller was named to take over. it was at -- if you look back at the statement that was made by rod rosenstein in naming mueller, it says he's to take over the investigation that comey had announced was going on in his congressional testimony when we became aware that this fbi inquiry was underway. that was a counter intelligence investigation. he adds that he was authorized as well to look into the question of whether there was collaboration between the trump campaign and moscow. well, fine. so we knew that was going on. it has never been the case as far as i could tell looking at the documents that the principle focus was this collusion question.
