Richard Nixon actually said...
So, because you represent a great country, a country with which we have had such friendly relations, because you represent a great continent, a continent so close to us, not only geographically, but in our hearts, and because, as an individual, you represent ideas that we need to hear and that we want to discuss with you, we welcome you most warmly today to the United States.
