Cleveland Cliffs offers to buy unionized mills US Steel is threatening to close

US Steel is at odds with the Biden administration over its proposed sale to Nippon Steel. The company threatened to close several mills if the deal falls through, but Cleveland Cliffs has offered to buy those mills if President Biden blocks the sale. The United Steelworkers union supports the offer by Cleveland Cliffs because they don’t trust Nippon Steel’s promises due to the absence of a contract with the union. President Biden is expected to announce his decision on blocking the deal on national security grounds soon.
