Harry Truman actually said...

"It is our duty, particularly here in Washington, to practice what we preach."

"I could not take the action which you request without reiterating these convictions with all of the emphasis at my command."

"The disclosure of all the evidence has vindicated my confidence in you."

"So, you stand before your countrymen after vicious and unwarranted attacks with integrity unscathed, with ability unquestioned, with honor unsullied."
