The STABLE Trade Policy Act, introduced by Senator Coons, would prevent presidents from unilaterally imposing new tariffs on NATO allies, major non-NATO allies, and free trade agreement partners. This significant limitation on presidential power would require White House trade actions to first pass through Congress.
The process would require presidents to submit detailed requests to Congress explaining their objectives, why diplomatic solutions won't work, and the expected impacts on both foreign policy and the U.S. economy. Congress would then have 15 legislative days to approve or reject the proposal through a joint resolution.
