An unusual move by the Trump administration to give itself a golden share in U.S. Steel as part of a deal to approve Nippon Steel's takeover of the well-known U.S. company could drive away foreign investors in U.

The U.S. Steel and Nippon deal continues to be a point of contention between labor and the presidential administration.

U.S. Steel’s so-called “partnership” with Nippon appears to be nearing its end after about 18 months after it was announced.

President Donald Trump would have unique influence over the operations of U.S. Steel under the terms of what the White House calls an “investment” being made by Japan-based Nippon Steel in the iconic American steelmaker.

The companies said they had entered into an agreement with the U.S. government to alleviate any national security concerns.

U.S. Steel shares rose 5% as Nippon Steel's $14.9 billion acquisition nears completion. The Trump administration approved the merger with conditions, including a 'golden share' to maintain American interests.
