George Washington actually said...

"It is perfectly clear to my understanding that the assent of the House of Representatives is not necessary to the validity of a treaty."

"I trust that no part of my conduct has ever indicated a disposition to withhold any information which the Constitution has enjoined upon the President as a duty to give."

"It is thus that the treaty-making power has been understood by foreign nations."

"The nature of foreign negotiations requires caution, and their success must often depend on secrecy."
