Lyndon Johnson actually said...

"Our people join with yours in mourning a servant of peace, and a friend of us all."

"Anytime, and whenever we think it is appropriate, on any question on which their particular qualifications may suit them."

"As long as I am President I will bend every effort to make sure that that day never comes."

"This country is not going to turn away from the upward course of prosperity or from the urgent hopes of peace."
