investigators may be wrapping up. the one thing that we had heard about that is that he was joining in on the people who were really unhappy with the ousting of the former ambassador to ukraine. what can you tell us? are these live pictures we're looking at here? >> yeah. yeah. but i can tell you mike mckinley has left the building. our team was following him as he tried to get out of that underground room a few floors below me after several hours of testimony today. mckinley, our understanding, came into this as something of a context witness. he was going to describe the situation at the state department under mike pompeo's leadership particularly over the last couple of months. we are told that he was particularly upset about the sidelining of marie yovanovitch, the now former ambassador to ukraine. and more broadly, the concern that the state department was being worked around by the white house, by rudy giuliani, and by other actors. mckinley was essentially a state department lifer. 37 years in the department.
