FILE - In this April 29, 1974 file photo, President Richard M. Nixon points to the transcripts of the White House tapes in Washington, D.C., after he announced on television that he would turn over the transcripts to House impeachment investigators. During the Watergate hearings many Americans were shocked by Nixon's liberal use of profanities on the tapes, which made "expletive deleted" a pop-culture catchphrase. (AP Photo/File)
