The excerpt I posted states that “several FBI employees who played critical roles in the investigation sent political messages.” If this comment was directed at only Strzok and Page, he would not have said “several”.
It could be that several of those employees aren’t specifically mentioned because they are potential subjects of a criminal prosecution.
Andy McCabe is certainly part of the Strzok-Page ring. The rarely mentioned Bill Priestap had to know.. he may have been among the first to sing. James Baker. John Carlin. Bruce Ohr.
Some are DOJ rather than FBI.
