Lyndon Johnson actually said...

"We are very proud and very glad to have you, and I am greatly honored to welcome you here to your house."

"I applaud the courage of those who are helping to help make and break new ground in this regard."

"In the courtrooms of the United States, you represent no individual but you represent the Government of your country."

"Our Nation's progress and the progress of all humankind toward equality of rights and toward opportunity is a steady climb and not just a big, quick leap."
