"I let them down. I let down... my friends. I let down... the country. And worst of all... I let down our system of government, and the dreams of all those young people that ought to get into government, but now they think: "Oh, it's all too corrupt," and the rest. Yeah... I let the American people down. And I'm gonna have to carry that burden with me, for the rest of my life... My political life is over."
January 1, 1970
