Cleveland-Cliffs is discussing joining with Nucor on a possible bid for U.S. Steel that is still likely months away from happening, according to people familiar with the matter. U.S. Steel had planned to sell itself to Japanese steelmaker Nippon Steel but President Biden earlier this month blocked the transaction over concerns about foreign ownership and national security.

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