Thomas Jefferson wrote the document called The Declaration of Independence and the Congress voted
12 - YAY, 0 - NAY with New York abstaining. "The business is done." John Adams said.
When the Declaration was agreed on, two days were allowed to "clean up" the document before it was
publicly announced on July the 4th. John Adams thought the great national celebration should be July 2nd because that was the day the important vote actually happened.
