US media report the government's "golden share" in US Steel after it's acquired by Nippon Steel will give the White House significant sway over the company's management.

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.

President Trump on Friday cleared the way for Japan-based Nippon Steel to potentially acquire U.S. Steel, though details about the structure of the deal — including a possible "golden share" held by the federal government — remain unclear.
