I made my mistakes, but in all of my years of public life, I have never profited - never profited from public service. I've earned every cent. And in all of my years of public life, I have never obstructed justice. I think, too, that I can say, that in my years of public life, that I welcome this kind of examination because people have got to know whether or not their president is a crook. Well, I'm not a crook. I've earned everything I've got.
— I am not a crook
by Richard Nixon
