For nearly a decade, the executive branch has abused the broad, highly discretionary tariff authorities Congress granted it throughout the 20th century. These abuses have imposed high economic costs on American firms and consumers; undermined the United States’ international standing; and fueled rent-seeking cronyism in Washington. Thus far, Congress has failed to rein in those abuses by reforming the underlying laws and reasserting its constitutional authority over tariffs and trade policy. To be sure, the political costs of limiting the executive branch’s powers—particularly concerning policies that benefit many well-connected, highly concentrated special interests and are simultaneously intertwined with sensitive issues like “national security” and geopolitical competition with China—are high for most legislators.
But what is indefensible is for Congress, knowing about the economic costs and political dysfunction engendered by executive tariff abuse, to grant even broader and highly discretionary tariff authorities to the White House—and this president in particular. Yet, that is exactly what Congress did on September 16, when the House of Representatives passed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026.
