The Smoot-Hawley Tariff Act of 1930 [1], where a Republican majority enacted extreme tariffs against President Hoover's almost veto, is sometimes considered one of the smoking guns for how the Great Depression got so bad. That's quite a precedent to be concerned about here.
(Though this version is dumber with the President trying to do it through EOs, which is probably illegal and Congress should probably be much more upset their powers to be stupid are being usurped before their eyes.)
