Richard Nixon wears a hard hat and speaks with a worker while visiting the Bethleham Steel plant in San Francisco, California

Richard Nixon was elected the 37th President of the United States (1969-1974) after previously serving as a U.S. Representative and a U.S. Senator from California. After successfully ending American fighting in Vietnam and improving international relations with the U.S.S.R. and China, he became the only President to ever resign the office, as a result of the Watergate scandal. "People have got to know whether or not their president is a crook. Well, I'm not a crook. I earned everything I've got."
