U.S. Treasury Secretary Janet Yellen said on Wednesday that Nippon Steel's blocked acquisition of U.S. Steel received a "thorough analysis" by an interagency national security review body that was sent to President Joe Biden.

U.S. Steel and Japan’s Nippon Steel sued the United States government on Monday in a last-ditch attempt to revive their attempted merger after President Biden blocked it last week on the basis that the transaction posed a threat to national security.

A first lawsuit was filed in the U.S. Court of Appeals for the District of Columbia Circuit, “challenging violation of the Constitutional guarantee of due process and statutory procedural requirements,” the companies said in a joint statement.

The companies argued in a lawsuit announced on Monday that Biden violated the Constitution by blocking the merger via a sham national security review that deprived the companies of their right to a fair process.

In dual lawsuits filed Jan. 6, U.S. Steel Corp. and Nippon Steel Corp. blame the Biden administration's politicizing its national-security review as well as the behind-the-scenes actions by rival Cleveland-Cliffs Inc. and United Steelworkers International President David McCall for scuttling the $14.9 billion deal.

Tim White has been working with an organization that works to overcome economic devastation long enough to be fully familiar with the word and when to use it.

The Vice-Chairman of Nippon Steel on Monday met with the mayors of the Mon Valley at Kelly’s Garage to talk about the Japanese company’s proposed nearly $15 billion acquisition of U.S. Steel.
