Cleveland-Cliffs CEO Lourenco Goncalves criticized the deadline extension keeping Nippon Steel's bid to acquire U.S. Steel alive months longer than originally intended.

There’s renewed uncertainty over U.S. Steel’s future after President Biden decided to block Nippon Steel’s acquisition bid, worth over $14 billion, citing national security.

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

Cleveland-Cliffs Inc. is partnering with Nucor Corp. to weigh a potential joint bid for United States Steel Corp., according to a person familiar with the matter.

U.S. Steel shares jumped Monday on a report that Cleveland-Cliffs is teaming up with rival Nucor for a potential bid for the company, whose $14.1 billion buyout by Nippon Steel was recently blocked by President Joe Biden.

Cleveland-Cliffs CEO Lourenco Goncalves said Monday he had a plan to buy U.S. Steel as he launched a tirade against Japan, calling the close U.S. ally “evil.”
