The words "cover up" only exist in the mind of the President. He doesn't have to say them to anyone else. He just guides them to the goals he wants to achieve, intimidates those who can be intimidated, moves those who can't be intimidated out of the process, and rejects a story he doesn't want in the official gov report. Clinton no doubt had ways to initmidate the disloyal elements in his adminstration. It looks to me like Clinton got a thrill out of lying and getting away with it, and the bigger the lie the bigger the thrill. It only caught up with him a few times, in sex scandals with Monica and a couple other women. No doubt Clinton got huge satisfaction from covering up a missile attack on TWA 800 and replacing the truth with a huge lie. Oh BTW, it makes a cover-up much easier if the President is a Democrat because the media always wants to agree with a Democract President and rarely does a serious investigation into a Democrat.
