Mr. GREER. It looked like a, I would say, a corset-type brace, maybe 6 inches wide, he wore it around his, down low around his, haunches, a little lower than the waist, probably, just probably below his belt he wore it there. It was something he normally wore, and I would guess, but I would say it was of a soft, maybe a kind of corset-type material, maybe elastic or something like that support. Mr. SPECTER. Mr. Greer, when your automobile arrived at Parkland, was there any medical individual awaiting your arrival? Mr. GREER. I can't remember--there were--who brought the stretchers out. There were some hospital people there, but who they were, I never got--I couldn't identify or knew who they were. There were some medical people there; yes. Mr. SPECTER. Where were they when you first saw hospital personnel? Mr. GREER. When I pulled into the ambulance entrance there were some people there on the right-hand side with these stretchers that they had rushed out. I don't know just who they were from the hospital staff. There was a great deal of confusion because everyone was trying to help, the agents were there. Mr. SPECTER. Are you able to state whether there was a doctor in attendance at that time? Mr. GREER. No, sir; I couldn't state that. Mr. SPECTER. What did you do after your arrival at Parkland Hospital? Mr. GREER. I helped pull it, take the stretcher into the emergency room that he was on. It is on wheels, and I helped to take that in, and I stayed inside the door of the emergency room most of the time while they were, the doctors were, working on the President's body. Mr. SPECTER. How many doctors were working on him in the emergency room? Mr. GREER. There were, between nurses and doctors. I would estimate there were, between 10 or 12 people, maybe not that many, 8 to 10 people in and out of that room. I don't know how many of them were doctors, attendants, nurses, and things like that with white jackets and they would come in and say, "I am doctor so-and-so." Mr. SPECTER. How long were they working on him there in the emergency room? Mr. GREER. I couldn't remember the time. Mr. SPECTER. You say you were with him most of the time? Mr. GREER. I was inside the door. I know, I kept the door closed most of the time, let doctors and nurses in and out while he was--while they were working on him. I stayed inside the emergency room door. Mr. SPECTER. Was there any special reason for you to leave part of the time? Mr. GREER. No, sir; I didn't go any farther away than outside the door. Mr. SPECTER. Were there any other Secret Service agents inside the emergency room at that time? Mr. GREER. Not at that time; I was inside the door. Mr. SPECTER. Where was Mrs. Kennedy at this time?
