President Donald Trump has ordered the Committee on Foreign Investment to review the potential acquisition of U.S. Steel by Nippon Steel. It’s a review that could have a significant economic impact on Western PA and the Mon Valley. In January, the Biden administration issued an order prohibiting the acquisition, after a review by the same Committee on Foreign Investment cited national security concerns. U.S. Steel and Nippon are challenging that order in court. Clairton Mayor Richard Lattanzi worked for U.S. Steel for 30 years. He says President Trump ordering the Committee on Foreign Investment to review the merger is a win for the Mon Valley and the greater Pittsburgh region. “You couldn’t create a better story,” Mayor Lattanzi said. “I thought the deal was great three months ago. Now, Nippon just said recently they may throw another $7 billion in.” Mayor Lattanzi says if the deal is approved, Nippon would invest billions in our backyard, hinting at what that could look like. “They just recently added some more promises to monies,” Mayor Lattanzi said. “I’m hearing rumors about a possible new battery in Clairton, a new hot mill at Edgar Thomson and possibly greener gas.” But environmental groups, including the Breathe Project, say talks of Nippon’s potential investments are vague and don’t address ongoing negative health impacts from outdated facilities or climate pollution.
