The first 3 presidents were British subjects and by virtue of signing the DOI they committed treason against the Crown, a felony punishable by death.
The Trump “felony” was contrived and a total fiction.
I just checked ... George Washington was not a signer of the Declaration. He made up for it by leading the Continental Army.
He presided over the Constitutional Convention; his signature is first on that document as President and Delegate from Virginia.
