Lyndon Johnson actually said...

"As long as I am President, I don't intend to give it up, or give it away."

"This order shall not apply to postmasters or rural carriers."

"I want any who may wish us ill to take notice this morning to understand that our beloved America cannot be divided by region, by religion, or by race."

"I want those who wish us well to know that America stands strong and stands steady, and stands firm, using its great power with great restraint."
