“Any person holding any office or any stock in any institution in the nature of a bank for issuing or discounting bills or notes payable to bearer or order, cannot be a member of the House whilst he holds such office or stock.”
— Third Congress of the United States Senate, signed by the President, George Washington
This rule keeps house from being influenced by financial decisions, bribery, and personal gain.
