What is a true statement about the us constitution?....well .... George Washington is not mentioned in the text of the US Constitution, however he was President of the Constitutional Convention, and a signatory to the document. George Washington became President of the United States by election a year after the constitution was ratified.
The oldest constitution still in use is the Constitution of San Marino established in 1600; nearly two centuries before the US constitution. and The US Constitution was inspired in part by the Magna Carta, but is very different in format and detail.
Thomas Jefferson was not a delegate to the Constitutional Convention which wrote the US Constitution; at the time he was the US Ambassador to France so had no part in writing that document..
