Nippon Steel expected to sue U.S. government over Biden block

What Nippon and U.S. Steel said in a statement: "It is shocking — and deeply troubling — that the U.S. government would reject a procompetitive transaction that advances U.S. interests and treat an ally like Japan in this way.

• "Unfortunately, it sends a chilling message to any company based in a U.S. allied country contemplating significant investment in the United States ... We are left with no choice but to take all appropriate action to protect our legal rights."

What Nippon and U.S. Steel didn't say: Anything about closing Pennsylvania facilities or moving the company's headquarters away from Pittsburgh, both of which were threatened if the deal didn't go through.
