What presidents added the fifth and sixth bill of rights and what year.?

The Fifth and Sixth Amendments to the United States Constitution were part of the Bill of Rights, which was adopted in 1791 under President George Washington's administration. The Bill of Rights, comprising the first ten amendments, was introduced by James Madison in response to calls for greater protection of individual liberties. Therefore, no specific president added these amendments; they were ratified collectively in the context of the founding of the republic.
