Who and What is the IRS?

Who and What is the IRS?: "In his article, Cooper cites the Federal Register and the Internal Revenue Manual acknowledgment that Congress never created a Bureau of Internal Revenue. Someone else has since located a Supreme Court decision where justices of the Supreme Court affirm that Congress never created a Bureau of Internal Revenue or Internal Revenue Service. Consequently, IRS has no lawful authority to enforce anything in the Union as Congress is charged with responsibility for establishing any government department or agency that the Constitution itself does not establish."
