Abraham Lincoln Supported an Audit of the then-Federal Reserve
This is from a speech he gave in the IL legislature in 1838:
"I am by no means the special advocate of the Bank. I have long thought that it would be well for it to report its condition to the General Assembly, and that cases might occur, when it might be proper to make an examination of its affairs by a committee. Accordingly, during the last session, while a bill supplemental to the Bank charter was pending before the House, I offered an amendment to the same, in these words: "The said corporation shall, at the next session of the General Assembly, and at each subsequent General Session, during the existence of its charter, report to the same the amount of debts due from said corporation; the amount of debts due to the same; the amount of specie in its vaults, and an account of all lands then owned by the same, and the amount for which such lands have been taken; and moreover, if said corporation shall at any time neglect or refuse to submit its books, papers, and all and everything necessary for a full and fair examination of its affairs, to any person or persons appointed by the General Assembly, for the purpose of making such examination, the said corporation shall forfeit its charter."
He's talking about the Second Bank of the United States, but at the time it was the equivalent of the Federal Reserve.
