Who receives the interest payment on the US debt?

This is just silly, its just numbers on pieces of paper...Not backed by anything.

So why don't you get Obama to write the figure of your national debt on a fancy piece of paper, and give it to whomever you pay your debt to........Then tell em to shove off....The debt is settled

Federal Reserve which is a PRIVATE GROUP OF BANKS.

The interest on the federal debt is paid to any person or entity that holds U.S. debt in the form of treasury bills, treasury bonds, and treasury notes. So that includes American citizens who purchase those treasuries, foreign individual investors that purchase those treasuries, as well as national governments, our own federal reserve, etc., etc.

One of the largest holders of U.S. debt is the Social Security Trust fund. You always hear that congress raided it, and that the money is gone. That's not quite accurate. Congress borrowed the money by having Social Security use its funds to purchase treasuries. So by law, that money is going back into Social Security come hell or high water. Either that, or the country defaults on ALL of its debt.
