Mr. Rowley. Yes, sir.
Mr. Rankin. Did you ever participate in such motorcades yourself?
Mr. Rowley. I have; yes, sir.
Mr. Rankin. How much?
Mr. Rowley. Well, I have participated, in rough numbers, over a period of 22 years—roughly, maybe, a thousand or more.
Mr. Rankin. Will you briefly describe the functions of the Secret Service agents in connection with the President's car?
The Chairman. Have you finished this other matter?
Mr. Rankin. No; I just wanted to——
The Chairman. All right. Go right ahead.
Mr. Rowley. When the President's car leaves the airport or a railroad station or any other location, the agents accompany him to the car and stand to the right and left, in the same order as their designated positions on the followup car, and screen him. And then the car moves out, slowly, because the rest of the cars have to have an opportunity to follow in the motorcade, so that none lingers behind, or is left behind. And then the agent in the lead car determines that the motorcade is intact and is moving, then he steps up his speed, which is a cue to the Presidential driver to step up his speed, and then they go at a speed consistent with the crowd that is there, and so forth.
