Evidently, the Federal Reserve holds the largest piece of the National Debt pie. Wonder how the twists and turns of the creditor-debtor logic set that up. Is the Federal Reserve a creditor of the United States ?! In what sense ?

        ‎"The public debt becomes one of the most powerful levers of primitive
       accumulation. As with the stroke of an enchanter’s wand, it endows
       barren money with the power of breeding and thus turns it into
       capital, without the necessity of its exposing itself to the troubles
       and risks inseparable from its employment in industry or even in
       usury. The state creditors actually give nothing away, for the sum
       lent is transformed into public bonds, easily negotiable, which go on
       functioning in their hands just as so much hard cash would."

Is the Federal Reserve's role as main creditor holding the National Debt as agent of the private finance sector?
