But don't forget to make something else clear. John Hanson was only the President of the Continental Congress, not of the United States. George Washington was the first President of the United States. And the first president of the Continental Congress was Peyton Randolph; not Hanson. Hanson served as President of the Congress for one year. After stepping down, he lived another year before dying in 1783. George Washington did not become President of the US until 1789. A half-dozen or so other guys served between John Hanson and George Washington--when the Confederation was abandoned in favor of the republic. The President of the continental congress had much less power than the President of the United States; who was the commander in chief, head of state, chief executive, chief diplomat, chief legislator, chief jurist, and chief politician.
But there are plenty of blantant lies in US history, that's for sure. The founding fathers were very conscious of what posterity would think of them.
