President Trump announced plans to double tariffs on steel and aluminum imports to 50%, effective June 4th, as part of his strategy to protect U.S. industries. Speaking at a U.S. Steel plant, he emphasized that the company would remain American-controlled despite a partnership with Japan's Nippon Steel, which is set to invest $2.2 billion in production and create 70,000 jobs. However, concerns from the United Steelworkers union about the implications of this partnership on national security and job security persist.
