John Kennedy actually said...

"I want to express my very warm appreciation to you, Mr. Mayor, for your generous welcome."

"Even though I have been here for almost 3 days, I am yet unable to make the distinction or see the difference."

"Political leaders come and go."

"So I am proud to be in this very ancient city, in this hall, which is connected with so much that was distinguished in history many years ago with lost causes like the one in 1848."
