Senator Cooper. Will you stand up and be sworn? Do you swear that the testimony you shall give will be the truth, the whole truth, and nothing but the truth, so help you God?
Mr. McDonald. I do.
Senator Cooper. You understand that the purpose of this inquiry is to inquire into the circumstances surrounding the assassination of the late President Kennedy?
Mr. McDonald. Yes, sir; I do.

Senator Cooper. Do you testify here voluntarily?
