John Kennedy actually said...

I want to express a very warm welcome back to the White House where all these gentlemen have come on other occasions.

For this government to tell our grain traders that they cannot accept these offers, on the other hand, would accomplish little or nothing.

I imagine that some day we will be welcoming them back, one or two or three of them anyway, who have gone a good deal further than they have...

I think that to say that this is the end of the road would be a mistake.
