We were waiting for the decision to be made what would happen, the vice President wanted to go to the airport, we wanted him to go immediately to Washington. We thought it would be best if he got out of the area. He didn’t want to leave Dallas without Mrs. Kennedy. Mrs. Kennedy wouldn’t leave without the body. And so when Vice President Johnson got to the aircraft, he just waited to find out what was going to happen.
Now we had the problem at the hospital of removing the body because Texas state law require there be an autopsy on any individual killed in that jurisdiction and the autopsy had to be conducted in that jurisdiction so we were not going to be allowed to remove the body from Dallas.
So we tried to convince them that this was the President of the United States, he represented all the people, and we should take him back to the nation’s capital but this was state law, and they were right, it was state law. So we tried to call a federal judge and a state judge, one of them came to the hospital. And after a lot of give and take, a lot of arguing back and forth between Kenny O’Donnell and Dave Powers and officials in Texas and Roy Kellerman, my boss, it was decided that if we took the body out of the hospitals and flew it back to Washington, it had to be accompanied by somebody who is a medical professional at all the time - at all times.
And I said, well, we have the right person for that job and it was Admiral George Burkley who was the President’s physician so from that point on, he remained with the body. The body never left his sight. And it never left my sight until we got to the autopsy room in Bethesda.
