Mr. Lawson. I don't believe I could give you an exact answer.
Mr. Dulles. In general what was your recollection?
Mr. Lawson. There were no PRS subjects, active PRS subjects which would be a threat to the President to our knowledge in the Dallas area in the files.
Mr. Dulles. And would you define PRS?
Mr. Lawson. Protective Research Section.
Mr. Stern. Was there a file that you yourself checked preliminary to your trip?
Mr. Lawson. I don't believe so.
Mr. Stern. Not a file of individuals but a file that might be helpful to you in your advance work for Dallas?
Mr. Lawson. We have files of past trips, some of President Eisenhower's. I am not sure how long ago they go back because they are probably taken out and put some place else periodically. But for example we have all of President Kennedy's trips right now plus President Johnson's current ones, and an agent could if he desired, if he was being assigned to a city, go and see if the President had been there recently, and look in that for names or perhaps if he was going to the same hotel or something, this would give him names of people to contact there. He might obtain information. There was no report on Dallas for President Kennedy.
Mr. Stern. You checked?
