Wisconsin Republican congressman Sean Duffy recently introduced a bill to give Pres. Trump new powers to raise tariffs in response to actions taken by other individual countries on American goods. This effort to expand the president’s power should make the White House happy, since Trump is eager to see his trade efforts bear fruit. But this bill will also move our nation back to the days of the infamous Smoot-Hawley Tariff Act of 1930.
