GAO presented a transcript of an interview with former Senator William Proxmire, a Democrat from Wisconsin, who served in the U.S. Senate from 1957 until 1989, as part of its program to record key government officials' observations and impressions and ensure that the bases for policy decisions and other important events are systematically recorded for posterity. The discussion focused on: (1) GAO service to Mr. Proxmire and Congress; and (2) Mr. Proxmire's views on how GAO can best continue to carry out its mandate in the future.
