Lyndon Johnson actually said...

"It must be clear to you, Mr. President, from the reception you received everywhere, the deep affection with which you are held here in America--your second home."

"But for understanding to prosper we need unity of purpose."

"This is the time for decision."

"Mrs. Johnson joins me in wishing you a very pleasant journey home and in sending you and Mrs. de Valera our abiding good wishes for your health and happiness."
