Mr. Specter. What are the standard regulations and practices, if any, governing such an action on your part?
Mr. Hill. It is left to the agent's discretion more or less to move to that particular position when he feels that there is a danger to the President; to place himself as close to the President or the First Lady as my case was, as possible, which I did.
Mr. Specter. Are those practices specified in any written documents of the Secret Service?
Mr. Hill. No; they are not.
Mr. Specter. Now, had there been any instruction or comment about your performance of that type of a duty with respect to anything that President Kennedy himself had said in the period immediately preceding the trip to Texas?
Mr. Hill. Yes, sir; there was. The preceding Monday, the President was on a trip in Tampa, Fla., and he requested that the agents not ride on either of those two steps.
Mr. Specter. And to whom did the President make that request?
Mr. Hill. Assistant Special Agent in Charge Boring.
Mr. Specter. Was Assistant Special Agent in Charge Boring the individual in charge of that trip to Florida?
Mr. Hill. He was riding in the Presidential automobile on that trip in Florida, and I presume that he was. I was not along.
