The root cause is the IEEPA (1977) which was vaguely worded to supposedly shrink executive authority under TWEA (1917) which allowed essentially unlimited executive authority "emergencies" to be declared for an unspecified amount of time. IEEPA was used to block TikTok, which still may get blocked, and used to set these arbitrary tariffs. IEEPA needs to be fully abolished. (And we also need to bring back the Tillman Act (1907) and get an amendment to overturn CU.)
