U.S. Senators Sherrod Brown (D-OH) and Bob Casey (D-PA) sent a letter to President Joe Biden sharing concerns about reductions in Section 301 tariffs, which are currently under interagency review by the Biden Administration. In the letter, the Senators cited the tariffs as an important means of combating anticompetitive behavior by China and other nonmarket economies. The letter also shared similar concerns about reductions in Section 232 tariffs, as well as related actions that would undermine American steel and aluminum producers as a result of negotiations with the European Union on the Global Arrangement on Sustainable Steel and Aluminum.
