Vice President Kamala Harris plans to publicly oppose the proposed sale of U.S. Steel to Japan's Nippon Steel during a Labor Day event in Pittsburgh, emphasizing the need for the company to remain domestically owned and operated. This stance aligns with President Biden's previous remarks about the importance of maintaining strong American steel companies powered by local workers. The proposed $14 billion deal has faced significant pushback from labor unions and political figures in Pennsylvania, a crucial battleground state. Harris's remarks will mark her first specific comments on the sale, reinforcing her campaign's commitment to American workers amidst growing voter engagement in the state. Biden and Harris's joint appearance at the Pittsburgh parade is aimed at energizing supporters as they approach the election. With both the Justice Department and a key cabinet committee reviewing the deal, the uncertainty surrounding its approval continues to loom.
