14. Richard Nixon decided to kill his critic
Richard Nixon has been the center of perhaps the most infamous scandal and investigation to surround the office of the President of the United States. No wonder it’s on our list of biggest US Government cover ups of all time. However, while everyone knows about Watergate, few know that Nixon had a long-standing feud with a journalist Jack Anderson. While Nixon initially only had Anderson followed, he later planned to have him killed off, and perhaps the only reason he failed to accomplish this was that the Watergate scandal broke.
