In 1975, President Gerald Ford's arms sale to Jordan led Congress to examine how to strengthen the Nelson-Bingham Amendment. A significant number of sale notifications had been allowed to be kept classified by the executive. The time period of Congressional review had been found to be deficient and the dollar level of $25 million as a tripwire had prevented a number of smaller sales from avoiding scrutiny. Members of Congress also sought to expand the scope of their review beyond government-to-government sales. The 1976 Arms Control Act incorporated these and other changes.
