On Screwing Our Political Enemies:

Nixon's Enemies List

On June 27, 1973, Nixon's advisor John Dean was testifying before Congress about the President and his "activities" and confirmed the existence of the enemies list. I have seen it written that there are 490 names on the list, or also 600 names on the list and that the names changed constantly. Here are some of the names I came up with , not in any order (except those denoted by number) because that's how I came across them. Enjoy.

13. John Conyers, Michigan Representative
19. Paul Newman, Actor
