Nippon Steel and US Steel have filed a lawsuit challenging the The Biden administration in order to block the nearly $15 billion deal for the Japanese company to buy American steel.

The lawsuit, filed in the U.S. Court of Appeals for the District of Columbia Circuit, asks the court to overturn an order by the Committee on Foreign Investment in the U.S. and President Biden to block the sale.

The companies also filed a second lawsuit against competitor Cleveland-Cliffs, its CEO Lourenco Goncalves and United Steelworkers President David McCall. It accuses them of illegally coordinating to prevent the transaction and undermine US Steel’s ability to compete.

“From the beginning of the process, both Nippon Steel and US Steel have engaged in good faith with all parties to emphasize how the transaction will enhance, not threaten, the national security of the United States, including by revitalizing the communities that depend on American steel, strengthening the American steel supply chain and strengthening the U.S. domestic steel industry against the threat from China,” the companies said in a prepared statement Monday. “Nippon Steel is the only partner willing and able to make the necessary investments.”
