Lyndon Johnson actually said...

"So long as I am permitted to be your President, we will continue to spend whatever is necessary to spend for the security of our people."

"You carry with you the gratitude of an advancing nation, and you take with you the appreciation and the friendship of your President."

"That remains our policy."

"The results of what you have done are plainly evident in the Congress, and will leave even larger imprints in the objective scrutiny of history."
