Nippon Steel Corp. and U.S. Steel filed federal lawsuits Monday challenging the Biden administration’s decision as ignoring “the rule of law.”

President Joe Biden's decision to reject a bid by Nippon Steel to acquire U.S. Steel isn't the first time friction over trade and investment has irked Washington's closest ally in Asia

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.

President Joe Biden on Friday announced his decision to block the $14 billion sale of U.S. Steel to Japan’s Nippon Steel, citing national security concerns. The move could have serious implications in Gary,

President Joe Biden officially announced on Friday he has blocked Nippon Steel's $14.1 billion purchase of U.S. Steel, setting up a likely federal court battle.

The steel companies allege White House decision to black takeover was political and violated their right to due process.

The companies condemned the president's decision and hinted at taking legal action, while U.S. Steel's CEO accused Biden of "political corruption."

Japan’s Nippon Steel emphasized that it is not giving up on its takeover of U.S. Steel, a day after suing the Joe Biden administration over blocking the proposed merger.

Japan’s largest steelmaker said that it would not give up trying to purchase U.S. Steel even after President Joe Biden blocked the $15 billion bid last week.

By blocking the U.S. Steel deal, Joe Biden showed he’s a Donald Trump mini-me on protectionism.

Nippon Steel and U.S. Steel are unlikely to convince a court to scrap President Joe Biden's decision to block their $14.9 billion merger, but their lawsuit could give them more time to reach a deal with incoming President Donald Trump.
