In 1973, Norvill Jones, a staffer of the Committee of Senate Foreign Relations, tried to interest members in establishing a procedure by which Congress could review large arms sales. Finding no takers, Jones mentioned the idea to Dr. Paula Stern, then a foreign policy aide to Senator Gaylord Nelson of Wisconsin, later the Chairwoman of the U.S. International Trade Commission (1984-1986). Nelson approved the idea and introduced an amendment for a one-house veto over significant arms sales. Stern and Nelson settled on a reporting "tripwire" of $25 million, the cost of a squadron of F-5E's. Nelson has credited Stern with conceiving the amendment and supplying the persistence needed to steer the attention of the Senate to arms sales. Nelson's proposed floor measure passed 44 to 43 in the Senate but a like House measure introduced by Representative Jonathan Bingham of New York was defeated.
