"The American system of government is rooted in openness. Article I of the Constitution provides that 'Each House shall keep a journal of its proceedings, and from time to time publish the same' and that 'a regular Statement and Account of the Receipts and Expenditures of all public Money shall be published' by the government. When combined with First Amendment guarantees of a free press, these provisions created the basis for open government. The Founding Fathers believed that openness was vital because the Colonies' disputes with the government of King George III taught them that participation of the governed could succeed only if the governed were well informed."
