Calvin Coolidge actually said...

"I don't quite throw my communications to the conference into anything like finished style or anything that perhaps would naturally be associated with a Presidential utterance."

"I expect to spend a considerable part of it trying to amuse the newspapermen."

"What I say here is not to be taken down in shorthand other than that which is taken down by my stenographer for my purposes."

"Otherwise it greatly interferes with my freedom of expression and my trying to disclose to the conference the things that I have in mind."
