An answer 6 years in the making.....

I'm on a plane right now, here is a useless little post just for you (and the whole internet)!
If you are out there Mr. Staggs (Spencer Staggs, just in case you search your own name on google) I can finally answer the question.

Though I must say it was sort of a trick question because he was the President of Congress under the Articles of Confederation which pre-dates the Constitution.
