Though George was a Freemason (see his Freemason apron above) and on their team it is telling that he went as far as to go on record mentioning the Illuminati by name. From the Library of Congress website, the full transcript reads:
George Washington to George Washington Snyder, October 24, 1798 -- Transcription
-Mount Vernon, October 24, 1798.
"Rev'd Sir: I have your favor of the 17th. instant before me; and my only motive to trouble you with the receipt of this letter, is to explain, and correct a mistake which I perceive the hurry in which I am obliged, often, to write letters, have led you into.
It was not my intention to doubt that, the Doctrines of the Illuminati, and principles of Jacobinism had not spread in the United States. On the contrary, no one is more truly satisfied of this fact than I am.
The idea that I meant to convey, was, that I did not believe that the Lodges of Free Masons in this Country had, as Societies, endeavored to propagate the diabolical tenets of the first, or pernicious principles of the latter (if they are susceptible of separation). That Individuals of them may have done it, or that the founder, or instrument employed to found, the Democratic Societies in the United States, may have had these objects; and actually had a separation of the People from their Government in view, is too evident to be questioned.
My occupations are such, that but little leisure is allowed me to read News Papers, or Books of any kind; the reading of letters, and preparing answers, absorb much of my time."
