Mr. Hansen. Before we begin the actual testimony, it has been our practice to explain to you very briefly what this is all about. Then if you have any questions that you want to ask before we swear you in, why do that too.

The President’s Commission was established by virtue of an Executive order of President Johnson, which was issued last year in November, and also of the rules of a joint resolution of Congress.

We have been specifically directed to investigate into and evaluate and report back to President Johnson on all the facts that had to do with the assassination of President Kennedy and the death of Lee Harvey Oswald.

We have asked you to come here today in particular, because after the FBI interviewed you, when they interviewed you, you indicated that you had seen Jack Ruby on, I believe, November 22, and also that you had worked in the section near his club and were generally familiar with him. So for that reason, we have asked you to come here to testify and tell us what you can about Ruby. But also to tell us anything else that you might be able to provide on any of the other matters we are interested in.

Let me also say this. Did we send you a letter asking you to come here?

Mr. Hansen. Yes; I have it in my pocket.

Mr. Griffin. Did you receive that letter 3 days ago or longer?

Mr. Hansen. I have been on a vacation, and it was given to me the 22d by my captain in the traffic division, Captain Thompson. I just come back from a vacation of 20 days, and I believe it was sent while I was on vacation, and they set it up.

Mr. Griffin. Let me see then, under the rules of the Commission, you are entitled to receive this 3 days before we call you to testify. Are you willing to waive that 3 days?

Mr. Hansen. I am willing to testify. I want to help you any way I can.
