George Washington actually said...

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

"It is a fact declared by the General Convention and universally understood that the Constitution of the United States was the result of a spirit of amity and mutual concession."

"I have ever entertained but one opinion on this subject; and from the first establishment of the Government to this moment my conduct has exemplified that opinion."

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