Mr. Adams. During that whole time?
Mr. O'Brien. That is right. During that period General McHugh at one point, Malcolm Kilduff from the press staff from time to time came in and out, Mrs. Lincoln, Dr. Burkley came in and out from time to time.
Mr. Adams. Was Dr. Burkley also in the emergency room?
Mr. O'Brien. I don't recall.
Mr. Adams. Now——
Mr. O'Brien. As we stood there, they moved equipment, heavy emergency equipment into the emergency room, and there was a great deal of what you would just envision—scurrying around of nurses and doctors, a great deal of activity.
Mr. Adams. Did you go into the emergency room yourself?
Mr. Adams. Taking it from the point that you arrived there in the corridor where Mrs. Kennedy was seated, how long a time passed before it came to your knowledge that the President was dead?
Mr. O'Brien. I cannot recall the length of time I had with specific knowledge. My impression is I had perhaps at the outset in the first seconds or minutes, I had some doubt this had occurred.
