U.S. Steel and Nippon Steel filed a separate lawsuit in the U.S. Court of Appeals in Washington, D.C., against the Biden administration to overturn the order and force a new review that could potentially lead to the deal. The Pittsburgh suit against Cliffs and McCall doesn't have any bearing on that decision.

If Cleveland-Cliffs is able to acquire US Steel, its CEO says the headquarters of the new entity would be in Pittsburgh, not Cleveland.

The bid by Japan's Nippon Steel to buy U.S. Steel may have a new lease on life after the Biden administration extended a deadline for the Japanese steelmaker to abandon plans to acquire the storied Pittsburgh company after President Joe Biden blocked the deal.

Takahiro Mori said Nippon Steel's proposed acquisition of U.S. Steel does not bring any national security risks, despite Joe Biden's insistence otherwise.

Ropes & Gray, Milbank and Wachtell, Lipton, Rosen & Katz all advised on the $14 billion acquisition. They're joined in two federal lawsuits filed in Washington, D.C., and Pittsburgh by attorneys from Reed Smith and K&L Gates as well as Mayer Brown.

President Joe Biden’s decision to block Nippon Steel’s acquisition of US Steel will go down as one of the worst of his presidency, and will tarnish

President Biden blocked the deal between Nippon and U.S. Steel earlier this month due to "national security" concerns.

Put together, U.S. Steel’s Man Valley Works plants are the largest single source of air pollution in the Pittsburgh region. Their fate, and 3,000 jobs, remain uncertain.

The move by Cleveland-Cliffs comes after the Biden administration blocked the U.S. Steel-Nippon tie-up on national security grounds.

The CEO of American-owned and operated Cleveland Cliffs says he’s putting in a bid to buy U.S. Steel. He says it’s not a matter of if, but rather when.

Joe Biden calls himself the most pro-union president in American history. But he’s punting a thorny union matter to his successor, Donald Trump, who may not have any better solutions than Biden does.

Nippon Steel Corp. and United States Steel Corp. jointly filed lawsuits in a last-ditch effort to preserve the planned merger of the companies, which was blocked last week by President Joe Biden.
