False: James Madison was just 25 years old when he signed the Declaration of Independence.

None of the Founding Fathers – George Washington, John Jay, Alexander Hamilton, and James Madison – signed the Declaration of Independence.On the third night of the Republican National Convention, Madison Cawthorn, Republican House candidate, claimed that James Madison, founding father of the United States and the fourth American president, signed the Declaration of Independence at the age of 25. However, that is not true. The Fourth of July celebrates the signing of the Declaration of Independence, the historical document through which the 13 American colonies severed their political connections with Great Britain and declared themselves to be the United States of America. None of the founding fathers signed the Declaration of Independence. 56 people, including Thomas Jefferson, Benjamin Franklin, and John Adams, signed the Declaration.
