About 320 officials from U.S. manufacturers, retailers and other companies and trade groups are set to appear over seven days of hearings that started Monday at the U.S. International Trade Commission before panels of officials from the Office of U.S. Trade Representative and other agencies. While some companies support the duties, most are arguing that Trump shouldn’t tax their products. The U.S. companies are lining up for the hearing to drive home a now-common point: Trump’s proposed tariffs are bad for business. (Bloomberg)
