Steam billows out of U.S. Steel's coke plant on October 25, 2020 in Clairton, Pa. President Trump placed tariffs of foreign-made steel in an effort to revive the steel industry. His efforts have drawn the support of many who work in the plant. While the tariffs succeeded for a short time to push down steel imports, create higher prices for domestic steelmakers, and to expand the workforce by about 6,000 jobs, by the following year those gains nearly disappeared.
